There's a "Moab checklist" somewhere I've seen on the site...check around for it, gives you tons of info.
And yes, you can go stock, as all the others have said, and have a great time, AND not destroy your VX. I went stock 1st yr, then just added slightly larger tires, no lift, for the 2nd year, did great. You can skip the harder boulder strewn trails (I do) and still have a fantastic time on many other trails.
Kenny posted the best Moab list I've ever seen.
