Ah- didn't see the second bit. As for adding anything, you won't need new track bars or control arms with a 2" BB. If you really plan to wheel it, you'll want (first off) a set of swaybar disconnects to improve wheel articulation. Being that you're in the Northeast, and rust/salt are issues, go JKS or Rock Krawler- their stuff each lasts pretty well up here.
Otherwise, if you plan to go to Pine Barrens or Rausch Creek often, I'd save up the extra coin and get a proper coil spring lift- BB's are fine and dandy going down the road, but off road, they do you very little good in the end- Mark W.
