I would suggest that you won't need to extend your front brake lines for a 2" lift, but relocating the existing bracket further down by carefully straigtening the 'Z' won't cost you anything if you do want to do it.
I think with 2" of lift also you may want to leave the trackbar until the lift is done and has been driven on for a couple of miles. It will then become clearer the exact offset you need to drill a new hole to re-align the front. It may not be far enough away from the original to do without welding a plate over.
You will need to adjust your draglink to straighten the sterring wheel after the lift. No parts though just sockets and some big mole grips or similar.
I wouldn't think you'll need degree shims for the rear on a 2" lift but if you are putting an order in somewhere you could get them as they are useful to have around if problems (vibrations) start.
I think that's about all you may encounter doing it. Just as general practice I would have plenty of WD40 or proper penetrating spray, some copper grease and loctite for re-assembly and some spare 8mm bolts for the bottom shock mounts. I think I also had to get a deep/long socket for the top shock mounts as my new ones had a long thread on them and the engine bay is too cluttered to use spanners.
Hope that helps. James
P.S. Ponyracer - can you get good deals on the RE lifts, just the 4.5 or is your shipping just a lot cheaper being military?
