1954 GMC 150-25First time classic project. Looking for tips and or tricks on tackling this job. Don't want to do something I don't want to be doing and damage or make something worse. Especially alignment issues with doors, fenders, hood, etc. No truck bed as it was a flatbed, might go flatbed or might go full size bed?

More little repairs I am getting into seems like it's taking longer or I am running into another issue. Decided it would be best to do a frame off restore since the parts I pull will have to be repaired or replaced.
Figured it'll be easier to redo brake lines, drivetrain, etc. after I wire wheel or sandblast frame, etc.
Only visible issue on the cab is the floor behind the fenders at the corner, I can see light and a tear behind driver cab (probably weld it back together). Open to ideas or suggestions.
What do I need for paint info if I decide I want to keep the stock color, unsure what the original color was on the outside, looks like it was brushed on.
Starting a logbook, photos and records of all parts bought or replaced.
So far I got started on was the rear brakes but did not do the hydraulics yet till lines get replaced. More I look at something else, I think darn, that needs to be fixed. At least I know the engine runs, but the wiring is shot.
Sorry for the rant. Anxious to get this started. Already looking for storage boxes for the parts, etc. Doing the work at my work as I'll have access to most tools and equipment, but cannot leave the truck in the shop. Sitting on my flatbed trailer while I am working on it. Should be able to put cab on a dolly and push under shelf out of the way.
