For Moab I'd definitely recommend a welded-on solution for the lower link arms on the rear axle where they attach to the frame and a good set of sliders.
Those lower link connections are prone to damage even on my 6" lifted 80 series with 35s with an identical wheelbase.
Agreed the lower shock mounts are next to useless, they may protect the bolt and lower shock itself but not much else and would make removal fun! May be a different story in a boulder field but at Moab the tire is going to lift with it unless you make a mistake a scrape along a rock, small chance if side slipping off a rock too but I wouldn't worry about those.
You can do allot of Moab stock, but in some areas, you may have to take some of the easier lines. I wouldn't attempt Top of the World in a stock height 250 though, too much trail damage and erosion from people who probably shouldn't have attempt it and have dug out many of the step approaches. TOTW is getting to be a fair difficult challenge with 6" lift and 35s now. TLCA recommends, front and rear lockers, winch and 37s and won't let you run that trail during a sponsored event with less than 35s, rear locker and winch. I'd image they will raise the requirement in the next few years if trail repairs aren't done.
