A very inexpensive method for transporting your bike in the bed of your Tacoma is to purchase something this: https://www.amazon.com/dp/B000AO7GRG/ref=cm_sw_r_cp_dp_T2_05dszbQ8H30KX
I bought 2 to transport friends bikes for a big event 4 of us went to. Screwed them to a piece of plywood and set it in the back of my F-150. Worked very very well. These are for traditional quick release axles. Amazon (and I'm sure your LBS) sells a version for through axle.
I definitely recommend a pair of shorts or bibs. For me personally it's bibs 100%. Since I got a set last summer, I haven't rode anything else.
Lock is nice if you plan to leave the bike unattended.
Waterbottles are a must.
A minimal set of tools so you can repair a flat and make adjustments on the road.
You do NOT absolutely need shoes or pedals right now. You can enjoy the bike as is and buy pedals/shoes when you are ready. Some shops will sell the bike with no pedals, others will include them. You can probably get them to throw in some cheap pedals with the sale to get you by for a while.
I also highly suggest a blinking head and tail light - as bright as possible. For day or night riding it'll help others see you.
Which bike did you end up deciding on? Your list in the other post was quite extensive and a very good list. Good luck!
This is exactly what I did.
The L brackets on the end are simply Corner Braces from the hardware store, and this is the fork mount I used.
I kept it about 1/8th inch longer so it could be wedged in, and stay put better.
And those are the bolt-in-the-truck bed fork mounts? This is awesome, I'm ordering the parts this week.
Edit Two of these They even make a 20mm axle adaptor for those of us with modern tech bikes.
You're welcome. I am hoping this fits.

There actually pretty heavy duty in my opinion too.
Lots of cheap options on Amazon. If you don't want the bar you can get a couple of these t-nuts that fit inside the track and screw the fork mount into that for an out of the way semi permanent options.
