Are you writing your first program? Check perldoc perlintro and http://learn.perl.org. Are you confused by Perl Object-Oriented system? perlobj should help. Do you want to know how to work with complicated (multi-level) data structures? Read perlreftut and perldsc.

You have already installed some modules; their documentation is easily accessible via CPAN website or using perldoc; what's exactly your problem now? Please ask more specific questions because such questions are a lot easier to understand and to answer.
