I've been looking for a while for a good source for small parts and tools to supply my home bicycle mechanic habit. I usually try my LBS first, but they often don't have the obscure stuff (like cotter pins) that I need. This outfit has 5 sizes of cotter pins, stainless steel pedal washers, spoke nipple washers, Stronglight crank extractors, and the list goes on. They sell in small quantities and cater to home mechanics. They're also friendly over the phone if you need some advice.
