Definately make sure you have camber adjustment. Caster is not a big deal as most people won't touch it anyways. You can't really go wrong with any kind of a-arm as they are all better than stock. Strong-arm, Lone-star, Houser, etc.. all offer good a-arms at a decent price. You can call Mark at HSD and get a package of Strong Arms and Elka shocks for a good price.
