Sheldon Brown is The Man when it comes to everything bike-like. He's even on these forums, so if you wander over the mechanical section, you can see his actual typing! Very exciting for us bike geeks.

We're here for questions, so ask away. By the way, you might want to invest in some padded cycling shorts. I wouldn't skimp on them. You touch your bike in three places: hands, netherregions, and feet. Take care of them all (and your head-wear a helmet).
