I wouldn't recommend AC kits, especially the coils which are notorius for blowing up shocks.

Instead, check out www.prgproducts.com and give Greg a call to answer your questions.

If you do a minor 2" lift, you won't need to extend the brake lines, just unclip the rear brake and ABS sensor lines.  But swapping the lines are not a simple mod, they are a pita, especially bleeding the brakes after you swap the lines.

Our trucks already have a forward rake (rear wheelarch is 1" higher than the front).  So if you lift the rear 2", you will definitely need to lift the front.  Since you are 4x4, the max lift in front should be 2.5" so you don't messup your cv angles.  If you want to go higher, you will need a kit that has a differential drop bracket like Calmini or Fabtech but those are big $$.  If you will be offroading alot, then anything higher than 2" in front will give you lots of coil bucket contact which can be annoying so an aftermarket upper control arm with a bumpstop is recommended.   If you have the $, I would recommend a good coilover shock like radflos which have an internal droop stop to prevent coil bucket contact.   If you go with a spacer lift in front, you keep your stock shocks.

In the rear, if you lift more than 2", then you will need longer shocks so you do not run the risk of fully extending your shock offroad, plus your ride quality will start to suffer.
