Ruby Sinreich and the folks at Orange Politics has created not only the best discussion forum about local politics at the main site, but also other very useful resources on their special elections page. Besides the candidate lists (with links to websites/blogs), there is information about filings and about registering to vote.

My favorite is Corey Reece’s Dynamic Election Map of Orange County, North Cackalacky made using the Google Maps API which pinpoints the registered residencies of all of the candidates. Corey has added RSS-fed recent articles from each candidate’s site (that make use of RSS).
