Ok here is what I did, I lifted my truck 2.5 in the front with new springs, and the rear 1.75 with new shackles, it sits almost exactly an inch higher in the back than the front which in turn makes the truck look perfectly level.
Now my suggestion to you if your looking for the front to look higher and have that cali lean going on, go with either a spacer from daystar or with lift springs depending on how much sag you have now it would be smarter to go with the coils. If you go with 2.5 over stock you can keep the rest stock minus the shocks once you hit 3 inches you need to get some upper control arms, or you can pick up some 3inch lift spindles and keep your stock geometry. Problem with upgrading spindles is that you need different rims
My mechanic had no problems with my alignment with my coils and right now im still riding on stock shocks, Im running 285/75/16 Definity dakota M/t's with no rub at all and I think they look good on the truck, I did upgrade rims but they still have the factory 5in bs but are 8in wide vs 7in so they stick out an inch farther than stock.
I installed my lift myself and was really easy, if you can change your brakes most likely you can accomplish the front end with ease and if your a little bit worried pick up a haynes manual and call it a day.
If you want to lift it higher look around I think fabtech makes a kit and just found out rancho makes a 4inch kit but I think its a little too much money and work for it, do a search because someone just installed it on here maybe a week ago
