Most lift "kits" relocate the axle below the springs. The minimum increase doing that is about 4". If you only want a 1" lift longer shackles are the easiest way to get that.
There is a set of monroe rear shocks that people like to use for the rear with certain lifts. I don't remember the number, but its posted around here a bunch.
The front wheel bearings on yours are serviceable.

Usually when you have to replace the rack boots it's a good idea to replace both, and make sure the inner tie rod end on the right side is not worn out or bent. Also if both boots are off you can clean any old grease and dirt from the rack (the actual gear shaft that slides in the housing) and put some fresh new grease on it to keep everything moving easily.
