NY Biker covered just about everything that you'll ever need. But I'll add one more item that I didn't see on her list...cycling socks. My feet are very picky about the socks I wear...especially on long rides. I'm partial to wool socks, as they regulate different temperatures very well. So you may want to experiment a bit with a few different types (and thicknesses) of socks out there to see what your feet feel most comfortable wearing.
