Great advice!! The only thing I would add, is to do a little studying about how your Jeeps suspension and steering components work, and how to fix them. It seems that there are far too many people up wheeling that think that they are invincible because they have 4 wheel drive, even though they might not know how to make it work! (Seen it on more than 1 occasion) And if you have a vibration, wobble, wiggle or whatever else the case may be, find out what it is before you hit the trail. If you don't fix it before you go, please bring some spares and tools so you don't ruin someone else's weekend towing YOU out.
