I would get it home, get it running, then be sure the brakes are great.
After that I would remove rust around the holes and paint with POR-15, then put a floor mat over the ones in the cab, and drive it.
Next would be the mechanical stuff, engine, transmission, front wheel bearings, and other mechanical stuff. During this time start to accumulate any sheet metal and trim parts you will need, but save them for installation all at once with the restoration of the body.
Then in several years once you have a great understanding of sheet metal and body work, then start on the cosmetic restoration. If you do that part first you probably won't be very satisfied with it in just a few years when you know more.
The mechanical stuff could be easier to nibble on as you learn, and cheaper to redo little bits if you have some difficulties while learning. The sheet metal you either get it or not, and because that's the part you and everyone else sees first you will want it done right the first time, and redoing it cost a bunch in just paint, not counting all the labor, or new metal if you really did a poor job the first time..
Two things to think about:
"If it is worth doing it is worth doing right."
and "If you can't afford to do it right the first time, you can't afford to do it over."
