The Camel Book is very good for beginners. Do the exercises they really help you grasp the concepts! I also use cpan.org a lot to learn about the different modules. It's good that you will be using Perl in everyday use. I believe you will pick it up pretty quickly. Good Luck!

Update: Sorry I mean the llama book (Learning Perl) not the camel book (Programming Perl). I have both. They are very good.
