Yep, PerlMonks :-D. Take a look through the Tutorials section, and if you have any questions, you know where to ask.

It's also worth looking at the Seekers of Perl Wisdom section. Many of the questions posted there will be obscure or way beyond your present knowledge, but many will introduce bits of Perl and ways of using it that don't leap off the pages of a text book. Be prepared to do some digging in the Perl documentation (see perlintro for a start then perltoc).
