I spent a ridiculous amount of time under that car. 1jz swap, suspension, full wiring harness from scratch - the works. Ended up being too much car for me so I sold it on, next car will be a z06. here's a picture of mine. It's a miracle that car never put me in jail.
Imported from US (Costa Mesa) to Norway in 2006. It took me 15 years to fully rebuild. Stripped to bare metal, welded, flat top pistons, Rebello head, Holley carb, LSD, poly bushings, big calipers front, maxima discs rear. Fixed the AC. Fantastic car.
One thing that could give an issue is Montana can be very smokey during that time, so just keep that in mind.
Bozeman has a very nice hot spring, its more modern, Norris hot springs a little more rustic.
Everything you mentioned is a great start.
