The folks at Sun & Ski Sports have created a handy Bicycle Care Guide with a checklist of regular maintenance for your bicycle. While I'd quibble with a couple of things (e.g. my chain is always dry on the outside) it's not a bad checklist. Via Biking Bis, also mentioned by Blue Collar.

That ride was gnarly... at least towards the end. I was dieing on the way home. It was bad... very bad. But I'm hoping to find a way to do it once a week or once every other week. For more than 6 years, I didn't own a car and did everything by bike. With a family now, it's a little harder to live that way... but I'd sure like to.
