Eric, I've done em on a genI, I can't imagine the gen II is much different - did remove the hub flanges to swap to manual hubs, and it looked the same in there...So:

1. When I eventually need bearings, I will buy genII 92 bearings (I can get you p/n if you need it)

2. Special tool: Yup, hub socket makes it way easier to remove the lockring, but you *can* use a screwdriver and a hammer. I have the tool if you wanna borrow it. Brass drift is good for knocking out the old race. Old race is good for installing the new race. You'll also need snapring tool to pull hub flanges... A torque wrench is recommended for tightening/loosening/tightening the lockring back up...

3. Bearing, and race. Are you doing inner and outer? If brake pads are getting down, would be a good time to change em, since you'll have to rotate the caliper up to pull the rotor, *if* you're doing inner and outer. And if you're pulling the whole assembly, might be wise to get the inner grease seal: cheapie part. Also, regrease the assembly with a high quality synth grease.

4. Hard? No. Not with the right tools. Biggest thing is clean out the old grease first, so you can see what's going on in there. Once you get it cleaned out, you'll see how it all goes together.
