Other stuff to replace while doing lift, locker

[idlingmike]

I'm going to be installing a rear locker and a mild lift soon. What else should I consider doing while I'm in there?

I've got the following...
1) Panhard bar drop bracket
2) Rear axle seals, maybe try to inject in fresh grease
3) diff carrier bearings
4) Fluid, duh
5) Pinion bearing? Do these ever actually fail?
6) Brake shoes
