My favorite CPAN package for doing things like this is WWW:Mechanize

It realy simplifies the task of writing scripts that log into web sites, click on links, fill out forms, and all the rest.

It takes a bit of time to figure out exactly how to use it, but study the examples and write some samples, and soon you'll be coming up with all sorts of excuses to write new programs with WWW:Mechanize.
