Good morning marscld,
in this thread, a lot of links how to do OOP in Perl were posted. But OOP can give you more than just a bunch of coding techniques. If you want to know more about the OOP backgrounds and how to use them, read a good book about object oriented analysis and design (e.g. I like the one written by Grady Booch), and maybe afterwards "Design Patterns" (Gamma/Helm/Johnson/Vlissides), and then maybe "Refactoring" (Fowler).
These books are not about Perl, but they helped me a lot. I haven't yet found similar books covering Perl. But as far as I can say, they are rather easy to understand, although they use C++ or Java as examples.
