Google does a Cheat Sheet guide to how to do advanced Google searches.
Also, I've had this link lying around for ages and I'm just about to try it myself. The GMail Drive shell extension. It turns a GMail account into an additional, remote drive. I'm intending to use it do access files from home and work (and anywhere I can connect my laptop to the Internet).
