Pathfinder is my recommendation, it is compatable with all of the D&D 3.5 and 3.0 materials (with some small adjustemnts) and you only need to buy one core rule book to play.
If you are unsure about spending the 50 bucks on the book, check out the Pathfinder System Resource Document. You can view the site or the downloads section if you want the PDFs on your computer. All of the rules are there so you can get familiar with them.
fierceDietyBro has the right idea. I've used the LFG forums on roll20 to find serious players for my horror campaign as well as join a group of light-hearted players with my Archer Sterling character. It's a great tool for any edition of D&D.
The beginners box is basically an easy setup for you and 4 or so adventurers, without the core rulebook. It's best used for someone that has never done any TTRPG and wants the foot in the door. For you it might be best to just look at a one-off with pregen'd characters, unless your players are also experienced in play of TTRPGs. It does give you a simple map, some pawn peices, and pregened characters.
So buy it if you want it for absolute beginners, or don't buy it since you have a Core Rulebook (CRB) and first beastiary. With those 2 things you can build a dungeon on your own. It might be best to get something like this:https://smile.amazon.com/gp/product/B07DBZ2FXF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1to draw up a map as well.
The Gamemastery guide will also introduce some extra GM things that could be included in your adventures, but it isn't necessary either for starting adventures, the CRB GM section is very sufficient for that.

If you've got an android phone you can't go far wrong with pathbuilder. Really easy to use character builder that is good at taking you through the process so you don't miss anything
You should be able to find at least one game every other day here.
Just be sure to act quick, particularly if its a new scenario.
Finding an online society game is dead easy. You can either had over to the Paizo boards, or join the pathfinder society online community Google group. The pfsoc especially has lots of games. Most nights you can even manage to swing a pickup game.

The easiest way to find a PFS game on Roll20 is to join the PFS Online Collective Google Group. People organize games there all the time.

A great Character sheet if you access to internet during play https://drive.google.com/templates?view=public&authorId=17085190382710658919#
What class/race do you want to play?
http://paizo.com/threads/rzs2m612?Guide-to-the-Class-Guides
But remember guides are great but play how you want your character to be!
Looking back, I now remember my first stat increase will go into Cha, then the rest will go into strength.
As tgrusz said, if you can find at least three other people who want to play, you can start your own PFS group. Paizo have a getting started guide: http://paizo.com/download/pathfinder/PFSOneSheet.zip
If you speak to your local comic shop, they may be happy for you to hold the games there, and may have an events calendar / notice board you can advertise the game on.
If you just can't get any thing happening locally, or while you get things started, you can also play online: https://groups.google.com/forum/#!forum/pathfinder-society-online-collective
Roll20 Warhorn is where you can see tables getting together online.
Roll20 is a virtual tabletop website geared towards pathfinder and similar game systems. This moves much faster than PbP and will normally get a scenario in at one go.
so single custom mini might be a bit harder than finding one already made. I buy most of my minis from amazon or ebay.
for example: http://smile.amazon.com/dp/B005MUAL8Y (this search was for dwarf mini)
On amazon be careful as some are shown painted but come unpainted. Also, just look at all RPG minis - no one is going to know if you have a D&D mini vs a pathfinder mini
Another place to look is the Reaper online store: https://www.reapermini.com/OnlineStore they have tons and tons of minis (most unpainted) but lots of selection and you might be able to find what you are looking for there.
I'm not sure what kobold fight club is, is that a 5E thing? The best player tool for 2E, IMNSHO, is Pathbuilder 2E I have sold people on second edition by showing them how easy (and fun!) creating characters in that app is. I also use /u/darthmarth28's Pathfinder 2E Autosheet for actual play in-game; if you're skilled at all at Spreadsheets you can customize it to do all sorts of nifty things for you automatically.
Lots of people swear by HeroLab, but I find their licensing too onerous, particularly when I already have to buy all the books for Pathfinder Society. Speaking of: you have posted this question to the Pathfinder Society subreddit, which is dedicated to discussion of the PFS Organized Play campaign. It's an excellent way to learn about and play Pathfinder, but if you aren't planning on playing in Society, you might get more answers to your general questions over in the generic subreddit: /r/Pathfinder_RPG
Amazon has the minis on sale right now.
So I regularly come with this fully loaded.
Top two bins have minis, medium/small/tiny minis up top and large or bigger in the second compartment. Bottom compartment has flip maps, books, pencils that I don't expect back, note cards, dice, back scratchers that can be used to help move minis from a distance, visa-a-vis markers.
Then I have a backpack with more core rulebooks, posters for my lodge, PFS numbers, custom PFS magnets to give to GMs in my area, a chromebook with pathbuilder on it, blank character sheets, note cards, laminated pregens, a map of Golarion, the Inner Sea World Guide (still need a physical copy of the latest world setting book) and 2-3 scenarios with signup sheets, chronicles, and handouts.
And because that isn't enough stuff, I also have a map tube with 3 chessex maps, or posters scaled of custom maps in certain scenarios.
If I am away from my local lodge I shrink it down drastically to a backpack and tube with drastically less minis.
There are six monster supplements for Pathfinder's First Edition that detail all of the demons and such. Golarion's cosmology gets pretty off the wall. The pocket editions of these books are pretty cheap and are great resources. Can't speak to the 2nd Edition stuff as I haven't purchased any of them, and the game is based off Pathfinder 1E.
There's also a slew of Pathfinder setting books that deal with the gods, demons, devils, etc.
There are many. :)
I would first checkout the:
Pathfinder Society Online Collective -and- PFS Grand Lodge - Online Play
>When is this coming to pathfinder? Both this and zeitgeist look amazing.
It was set as part of the stretch goal for this kickstarter, but i don't know exactly when it will be ready. I'm super excited about it though!

One of the hardest things, especially for new players (and often in PFS Organized Play) is being able to create and roleplay characters that are distinctive and have an interesting appearance, personality and approach.
Creating unique characters is a great way to create better roleplaying experiences and help characters stick in player's and GM's minds, and helps us to avoid the 'I'm just a barbarian with a big axe' generic approach!
Coming up with a unique character concept can be overwhelming though. That's why I made this easy to use one page sheet that will allow a player to quickly capture the key aspects of their character's appearance, upbringing, approach and attitude and will help create distinctive, unique, vibrant, one of a kind characters.
I have deliberately kept the sheet and details captured 'light weight' as this is mainly intended for organized play, although you are of course free to adapt and amend it to the needs of your players and groups.

This is a good 1st ed generator https://www.wolflair.com/hero-lab-classic/
And for 2nd i really like the phone app pathbuilder2 https://play.google.com/store/apps/details?id=com.redrazors.pathbuilder2e
"a physical copy of the book, a name-watermarked Paizo PDF of the relevant pages, or either a photocopy of the relevant pages or electronic access to the Pathfinder Reference Document along with proof of purchase. Proof of purchase may include a receipt from a game store or a screenshot of your My Downloads page on paizo.com."
The best way, by far, is the PDFs. They are cheaper, searchable and bookmarked, and don't crowd a smaller tablet. If your phone is lacking room, you can pick up a cheap flash drive that plugs into your phone and put them on there.

After I ordered a mini from Heroforge and it broke within two weeks, I decided I needed a carrying case to protect my minis for PFS games. Here is the one I bought.
Haven't had a broken figure since.
I used to use a 14 mini case I got from Chessex, but it ended up being too small for the number of minis that I have to transport. So, I upgraded to a soft sided case from Amazon. Feldherr MINI 32 miniatures Figure Case https://www.amazon.com/dp/B008VO4DYG?ref=yo_pop_ma_swf
You may need to make some strategic cuts to accommodate minis that are wider than their base, but it works relatively well. Highly recommend it.
If you don't mind the cute look. Ninja Division Miniatures and my go to for personalized minis is always Heroforge.
I'm sure there are some in the Inner Sea World Guide and if you get the pdf you can probably blow them up. I doubt you will be able to find them online somewhere as they are probably trademarked by Paizo.
Hope this helps!
I have three battlemats. While I'm doing DM prep for a PFS scenario, I draw out the battles, one to a map. When it's time for battle, I roll out the correct map and away we go.
I use different color markers for details like water, vegetation, walls, trees.
I cannot recommend enough the Pathfinder Beginner Box. It gives you an adventure (with a few free ones available for download from the Paizo site), a map, a condensed and well explained version of basics of Character Creation (only 4 classes (fighter, cleric, rogue, wizard) and 3 races (human, elf, dwarf), though a 5th class (barbarian!) is also available for free download from the Paizo website), awesome character and monster tokens, character sheets (though, again, these are available for free download)... literally everything you need for levels 1-5 adventures.
I have the beginner box and I would happily pay much more than the $23 that amazon is asking for it, but at that price it is an amazing bargain. I've used it to introduce newbie friends to the game, I've run the beginning adventure nearly half a dozen times, and each time the new groups find new, fun, and amazing ways to throw me for a loop.
If you decide to go with this, you will not regret it.
If you are hand drawing your maps I recommend http://smile.amazon.com/Chessex-Role-Playing-Play-Mat/dp/B0015IUAAG/ref=sr_1_2?s=toys-and-games&ie=UTF8&qid=1444764469&sr=1-2&keywords=chessex
You can also print the maps from PFS modules, I normally scale it with GIMP so that the squares are the size needed (normally 1in x 1in) and remove GM information. This can be costly, but if you replay it with another group and you had your printed map covered you can reuse them.
There are miniatures available at comic book stores and online or you can use board game pieces, beer bottle tops, dice, or even paper.
I like the roll-up dry erase mats like http://www.amazon.com/Battle-Erase-Sandstone-Markers-Eraser/dp/B0058QEZCU
Re:NPCs, yeah you pretty much have to improv a bunch of characters all the time as GM. It pays to prepare a little but mostly it's improv based on the loose notes from the campaign book. I usually go to the mat when everyone starts rolling initiative, unless the combat maps are already given in the module.
The grippli I see listed in Bestiary 2 has a 20' climb speed and is small. There's also a monkey goblin in the Inner Sea Bestiary if it's specifically the world guide that's a problem. There's a few more medium size I spotted too (morlock in Bestiary).
(This pathfinder monsters OGL app is pretty handy for stuff like this. Used it a bunch for the monstrous physique loving magus I built for a one-shot a while back.)
