Definitely read The Camel. Not sure the Lama is so important if you have a little programming under your belt. But also get a copy of the Perl Pocket Reference! Whenever you can't remember the syntax for something the Pocket Reference is far and away the quickest way to find it (unless you are using something like Komodo with CallTips turned on).

And, as others have suggested, hang out at PerlMonks. Read the tutorials. Ask questions. Chat in the CB. Answer questions - there's nothing like answering someone else's question to learn how to do something :).

Enjoy your time with Perl.
