Hi John,
Welcome to Moz. We are glad you are here! You asked a great question, and have already received some solid advice. See how friendly folks are around here? A similar question was asked last week at http://moz.com/community/q/make-the-most-of-moz. You may want to take a peek at it, as Peter Lunn and Cyrus Shepard linked to some excellent resources there.
Cheers,
Christy
