Phil Zimmerman has a regular series at Cadalyst online (it may also be in the print magazine, I am not 100% sure) that is worth bookmarking and reading, especially for new users.

Other topics in this series can be found at:
Check them out and print them for your in-house reference binder!
I beleive that Mike Choquette (who works at Imaginit aling with Phil) also contributes to these CAD Clinic posting.
These articles are typically not in the print version.
