there's also THIS thing for fauxspresso, but I've not tried it.
Some people love to cook when backpacking... and yeah, it's nice to fry up some eggs and bacon in the morning... but it's an effort to bring fresh food and keep it safe, and cleanup afterwards... so for a lot of people it's Mountain House or Backpacker's Pantry freeze dried meals. Heat water, eat out of the bag, add more water and drink the leftovers, and fold up the bag and store in a ziploc. That way you can get out there with a small stove, a pot to heat water and drink and not really worry about cooking. It's a bit expensive though, so some will buy bulk freeze dried or bulk dehydrated and work with that, again doesn't require much cooking. There's even a sub dedicated to it, r/trailmeals I think.
Coffee is a problem. With LNT ethics, you're not supposed to throw out the grounds but carry them out... but it's a bit annoying to be carrying wet ground for several days. And it's messy. I like good coffee, but I used to just use some Nescafe instant. But for the past few years I've been using Starbucks VIA packets. When I'm car camping I'll bring a nice Bodrum French press, I've also got a GSI Lexan press. But backpacking I just don't like dealing with grinds so I'll use the instant. Some people like the Minipresso, I've thought about it but in the end the Via packets work well enough for me.
As for organization... checklists are your friend!
REI has a pretty good checkist (printable PDF available)
It's pretty extensive and you don't need everything on the list, but it's a good start. Getting a little notebook is good to... when you encounter something you weren't prepared for, make a note. If someone gives you a good tip, make a note. When you get home, make some time to do a quick trip report... where you went, what trails you did, things you noted in the book, things you want to remember for the next time ("couldn't remember how to tie a clove hitch, watch more videos" or "wet toilet paper really sucks, double bag, bring two packs, keep one in the top pocket of the pack!"). Make notes about your gear, what you found worked well and what you really didn't like after a few trips, it'll help give you a better idea of what you might want later when you start replacing or upgrading your gear. And 10 years from now you'll be clearing out the gear closet and find the notebook and have a laugh at how hard some things seemed to be.
Trip reports are also helpful when someone asks for more info about a trail that you've been on. If you did it several years ago you may not remember all that much about it, but looking back at your TR you see you made a note that the trail maps show a water source that's no longer there, a rock slide which you need to steer around. And it's nice to go back and read your own trip reports once in a while and again see how you're progressing.
Heh heh... mother nature is a cruel mistress... be careful how much of a challenge you want to take on! Since you're the team leader, you need to keep in mind your goals, but also set specific bail conditions. Weather, health, gear failures... if something doesn't feel right, don't be afraid to bail and try again next week when the conditions are better.

The Minipresso with a hand grinder is my go to. For portable coffee. I actually carry one on the daily in my bag to work.

Don't know about the states so, but I have the minipresso and it's great! Obviously it's not the same as a true espresso machine but for the price it works!
