Boomer,
I too have been where you are and although you hit many of the points, I can add a few to your “Need-To-Do” list. First, I have a build thread going over at the 67-72 truck club BB Click link below – read it through) you will see what I was up against. I am restoring a ’60 GMC from the ground up been at it 12 years this year, Hurricane Katrina interrupted the entire process by drowning the “almost painted” truck, back in 2005. Been making steady progress ever since. I've used the sand blaster. Sode Blasting ands Chemical Dip method, all work well, (chemical is the best,IMO). You'll see pictures in the links.

I’ve taken apart 3 trucks trying to make one and had one stolen on me. Trust me to not set your time table to short, you’ll get discussed and thrown in the towel. Think about all the fun you will have working on it.
Go to a lot of car show meet and hook up with other 60-66’ers and form a friendship, many of the guys and gals will be glad to lend a hand on the project. I’m always offering labor and some work, cabinet blaster, etc.. Matter of fact I’m getting ready to offer a feed bag to the local guys to help me get the doors adjusted and the fenders on. My sons moved away and I’m by myself, so I NEED HELP. Cook up a good meal, buy some beer and call them over to assist. They WILL come to help.
