Washington Area Bicyclist Association (http://www.waba.org). Tons of info about area trails, shopping for gear and biking laws. Also, take a peek at the commuter convoy routes from May's Bike to Work Day to help figure out the best way to ride.
Capital Bikeshare (http://www.capitalbikeshare.com). The new program has 1,000 bikes at your service, ready to rent throughout the District and Arlington. Even if the locations don't make it convenient to bike to work, they might be useful for biking at work.
