I have an older Trek, and I just got a decent deal on a Fox RLT (80mm) fork. I need to know a few things.

One, how do I go about removing the bearing races from the frame and fork steerer?

Two, how do I go about choosing a headset to bring it all together?

Last, the bike "looks" just a touch high in the front from the forks. Is it possible to reduce the travel slightly?

Thanks for any tips.
