Get a professional model hub/drum puller for hte rear brakes (J.C. Whitney had a decent one for a fair price).

Rust and engine needs rebuild...

Not only will you be able to dis-assemble and reassemble blindfolded, you'll get plenty of practice!

Anticipate fully tearing down and reassembling everything in the brakes, suspension and steering just to make it truely road-safe.

Engine sounds to be speaking for itself!

Get radiator rodded out.

At least open tranny top cover for a look inside and scrutinize the oil that comes out. Not many rebuild options but some parts are still available such as dog keepers, bearings and syncro-cones. No lay-shaft stuff (alas).

Ditto for the rear-end but bits are more readily available.

Expect to have to remove the heater to dig the crud out of the plenum and replace the drain hose!

Enjoy!
