You don't want to do a 3" body lift. It causes all sorts of issues and doesn't give you any more ground clearance anyway.

Best compromise for you is to do a 1-1.25" body lift and a 1-2" suspension lift. 1" body lifts don't usually cause too many tough problems to deal with. A 1" suspension lift can usually be done with lift shackles. Some add-a-leaf helper springs may give you an extra inch which may be not so much of a lift as much as helping your sagged out oem springs back to their original height.
