Seeing that you have an 01 4x4 offroad just like me, your tow hooks will have to be removed, or you will have to cut the valance. On bills (04lvl2) we didnt have to remove his hooks, but every other truck we did.
The front hitch would not come out in the normal spot, you are moving the body 3 inches higher then the frame, so things will not align the same.
Im sure you can make some kind of heavier brackets for the back bumper, but i would not reccomend doign that. I would just buy a hitch or make your own. The bumper seems very week after the lift.
With the P/A body lift kit, they give you all the hardwear to lengthen what ever is needed. abs lines and brake lines are fine from the factory. You have to extend the gas filler neck line which they give you in the kit, and a few grounds.
The radiator is still "safe" with it lowered. The valance covers it. I put a skid plate in the front on my truck so it is "more safe"
The a/c lines...i dont remember touching these or rebending them.
What plug on the passanger side are you talking about?
