Check out your local high school or Vo-tech, they both offer night classes in basic auto mechanics and you work on your own vehicle.
Sears Craftsman tool kits, find a 200 or 300 piece tool kit there, buy it and a good tool box, if you have the room get a 6ft tall one, Sams club, Lowes, etc have decent ones as well as Sears. My parents bought me a sears pro 3 piece, 7ft high, I figured it would work forever, that was 20 years ago, I out grew it to overflowing about 10 years ago.
Torx socket set, just buy them all up to T55 or T60, you will eventually use them.
Floor jack and 4 jackstands, again sears and get a good one, your ass is going to be UNDER it so don't skimp
Factory Service Manual for your vehicle.
Find a local jeep club after you get what you get and start hanging out with them, participate in lift parties where a dozen people show up and 4 of them actually know what they are doing and guide the rest.
