You are fine with that set up. Trim the front body mount, remove the mud flap and go. I don't think you need extended brake lines with this set up. If the rear line is short, just remove the bolt that holds the bracket to the diff, carefully bend the line and make a spacer to re-attach it to the diff. You won't like the ride with the DR's cranked up to 3.0. Mine are at 2.5 and ride good. The LT kit widens up the front track width. Then you are looking at body panel mods. If you need more lift, consider a 1 inch BL.
