Everything about the truck's future depends on following the advice given above for evaluating its condition. You don't say you flat-bedded it, so if you flat-towed it home without lighting up the tires or skidding the front tires through turns, the running gear can't be locked up and the steering probably moves at least some. That would be good.
From another, '...not a mechanic...": I can tell you that it's a simple, honest vehicle to start on. I might not start pulling the engine apart myself, but I'd drop the pan, open up the brakes and wheels, and do the other checks on my own. Start shopping around for a local
real mechanic (not a car dealer parts swapper) who you can call on for advice and to give jobs you can't or handle or have the money to sub. The more you know walking in the door, the better you'll be able to evaluate him and get an idea of price-to-fix.
Perhaps this will not be talking down. Buy a case of PB Blaster or Kroil on sale (and/or a can of the liquid and an old-style,
puck-a-puck-a thumb-on-the-bottom oil can), a couple of hammers from tap-tap-sized to up to BFH, a torch (even a propane turbo torch) and a fire extinguisher. The manual hammer-drive impact sets can be very effective at about $30. Using that stuff is better than snapping bolts. Rule of thumb if you need to buy tools and select Harbor Freight: Buy on sale and buy 2. If the wrench snaps or fits crappy, you have a backup to get through the day. Much as I'd rather buy the good stuff, that method has gotten me the stuff I needed at a steep discount from the good stuff. If you buy jack stands, consider the 6 tons because they're taller. Your M37 has a lot of ground clearance and the height will pay off. Cinder blocks and the like are verboten. That's a 3 ton truck.
Determining success factors are bank account, determination, imagination, patience. I really want to hear (and see photos) of your progress.
