3in lift help
 

I want a three inch lift but I hear lots of ways. I want to replace my front shocks, springs etc. Truck has almost 100 thousand miles and the front end has nvr been touched before so its time it gets a tune up anyways. Ant advice on the best approach to this? Also the leaf springs in the rear. Should I do away with them altogether or just block it? Help plz? It's 09 2.3 xlt.
