Kenny,
In the past I've put together some perl code that extends
LWP::UserAgent. I override or add a few methods using
HTTP::Request::Form, HTTP::Cookies, and HTML::TreeBuilder. The end
result is that you can come up with an enhanced useragent that lets you
fill out forms, handle cookies, and parse HTML output. I recommend
looking into the modules I mentioned if you haven't already. I noticed
that in my code using my extended user agent, I also used
HTTP::Request::Common and URI::URL. All my Javascript parsing was done
by looking at the javascript code and simulating it, though (usually it
was just putting together a URL in a straightforward fashion).
