Do I need extra parts for rear wheel bearing replacement

[442nd986s]

First and foremost.....Greetings from the desert.
So I'm planning on replacing both of my rear wheel bearings upon my return from my deployment. Before I left I had the car checked out by a local mechanic and was told it sounded like right rear bearing is goind out. So I figured might as well do the left side also and at the same time, since the suspension is pretty much out, also put in new strut and brakes. My question to ya'll is: What other wearable items should I replace while the suspension is out? Any other seals, rubber gaskets, etc. I want to have everything ready for him and not delay the momentum. Do what the mechanic to say: "oh, you will also need...blah, blah". I like being prepared.
