Oh, and there are some good podcasts, too. Like Risky Business, 7 minute security, Liquidmatrix, Security now... 7 minute security just had a decent series on how to set up a DIY $500 pentesting lab, for example (https://vimeo.com/179271256).
Finding some famous pentesters to follow on Twitter can't hurt, either.
