4X4 Lift Questions

I am going to move my lift from my old truck to my new 4x4. I need to know if I need to do anything different on the 4x4. (Dif drop, brake lines)
I want to get a new set of leafs too. So the set up will be icon coilovers rear res shocks and new rear leafs. oh and tc uca's. the coilovers are not dailed up very high so I am thinking 2 maybe 2.5 inch lift. I need to get a spanner wrench, Torque wrench, Loctite, and some rear leafs too. any suggestions or knowlege please speak up. thanks

 

That's a great choice of quality parts, what are your plans for the truck? What do you use it on terrain wise?
