Welcome. Mosquito Pass is very pretty. So are Shrine Pass and the Camp Hale Area. I get my stuff from Slee Off Road. Just start driving and you'll figure out what you need. I would get a fire extinguisher, 12v air-compressor, high-lift jack, towstrap and big D rings. There is a good thread on Recovery gear. Big tires and lift kits will just get you stuck further away from home. Experience is more valuable than any upgrades.
