Books to master Perl, LAMP and web development
Or, alternatively, use perl monks and perldocs.
IMO it's usually more difficult to become a better programmer than to learn a specific facet of programming, or a programming technique, so before you start trying to become a master of OO and web development, pick up a copy of Perl Best Practices, which will help you learn to right more readable code in any language. This, in turn, will make it that much easier for you to really understand what it is that you're doing, and ask for help when you get stuck.
Focus on the fundamentals, and you'll find that it's that much easier to move on to specific techniques.
