Steve R, SFA would increase articualtion, less lifting of the tires when wheeling. But would you want to do that to a late model rig? It's one thing to buy an old IFS Rig and convert, but on a 50K plus rig like a Hummer, I'd consider a front ARB first, and protection from trail rash.
As far as lift. pick your tire size and only modify enough for it to fit. Anytime you lift, up goes the CG, Suspension lift is bettet thanm body lift. All depends on what you run with the rig and how much you want to spend. Crash by far is much more knowlagable in supension design than I am, maybe he will add something.
The best mods for the bucks are tires, lower gears (Diff or Tcase or both), and lockers fr&Rr
