I am still at a beginner level and have finished the book "Beginning Perl."

I recommend you read Modern Perl next, hang around here answering/asking questions and if you have the stomach for it come over to irc.perl.org and join a few channels.

Additionally, if you can get yourself to Asheville, NC at the end of June, you might want to attend YAPC::NA, it is a really great way to meet people and learn Perl. And it is pretty cheap too (as far as conferences go that is).
