The only thing I'll add in addition to the good advice so far, is in relation to this:
At what point do you restore/rebuild parts? Meaning, do I just take everything off, bag and tag, and put it away; leaving the rebuild until I am ready to assemble? Or, do you rebuild items as they come off and then store them until reassembly?
Its probably a personal decision based on your personality, but here is my take on rebuilding -
Do it as the items come, don't wait until you are ready to assemble. There may be a few exceptions (engines being one of them) but I try rebuild as I go. The reason is pretty simple - As you get closer to finally getting done, or the car started, or whatever major milestone you are approaching, its a royal PITA to have to stop and rebuild some rusty, oily, caked-in-dirt "thing-a-ma-jig" every two seconds. Its virtually guaranteed that you'll be heading toward to major assembly and...."oh look, you forgot to rebuild or restore that needed part".....There's few things more frustrating that when you can just about see the light on a build, yet find that you're having to stumble over stuff you forgot to fix, restore and rebuild - especially if you find some of those parts are beyond salvage, and you waste even more time waiting for a new one. For me its also a bit of a downer to have a mountain of rebuild work ahead - I don't mind it in small batches, but when I know I can't even start on A, until I rebuild B, which will require cleaning and upgrading C, that can't really happen because I'd really need to do D, E, and F first......sigh....I end up not bothering, and overall the project just stalls.
So, what works for me, is to rebuild and restore things as they come, and that way I know I'm good with the parts (or have plenty of time to get a new one). I can tackle the rebuilds without feeling like I'm drowning in constant refurbishment, and as a side benefit - you start to see a growing collection of restored parts and pieces, which keeps me a lot more motivated than an ever growing pile of disassembled bits. I also try vary the work where possible, don't let a single area kill your morale.
Regardless of how you do it, good luck, and remember that there will be good days and bad - just keep your eye on that first cruise when the job is complete.
