Jeeps have a lot of torx bolts, T55 mostly if I remember correctly. Having a set of torx bits will definitely help out with mods, but for the most part, there are not many specialty tools you'll need unless it's a specialty job. Just everyday/weekend tinkering will only require standard tools: wrenches, ratchets and sockets, screwdrivers, a good rubber mallet for whacking stuff, and maybe some duct tape. You should be good to go with that. Buy American if you can!
