Hi Jemz, great that you're interested in Perl! It's a powerful language, with flexibility as probably one of its strongest points, along with a great community and constant updating.
Ovid has an excellent, newish book called Beginning Perl (link is to an ebook, I have the paper book), which I can recommend. The original "Llama book" misses some important things like references, and Ovid's book is written with Modern Perl in mind (so you aren't led astray by things that "work" but aren't actually a good idea in Perl land... not that the Llama book does this!).
PerlMonks is, despite how it looks (that's free everything there, which is why there is little incentive to update that infrastructure), still the best place to go with Perl questions, but the Perl community is now pretty active on StackOverflow so that should be a safe place to ask questions about Perl in general.
++ to toddy's link, learn.perl.org. This was set up by the community specifically to fight back against crappy old Perl code being offered to newbies, like Matt's Scripts. You can be sure most or all of the tuts on learn.perl.org will be "modern" and best-practice Perl.
Catalyst is complex. I would totally wait on Catalyst until one has more than basic Perl under their belt.
If you want to quickly run a webserver, instead of Catalyst (which is a large, comprehensive, does-everything uber-framework) I'd recommend Dancer, which in the beginning was based somewhat on Ruby's Sinatra (and so is also similar to Python's Flask), a really minimal webby thing to get a webserver up and running.
Dancer 2 has made many improvements from the basics used by Sinatra, like removing globals so we can run multiple instances at once, and you know, concurrency is the hip new thing these days
Check out the Github but of course you can install it easily via CPAN. (well, actually, on windows I have no idea what's easy, but I'm sure Dancer can run on a windows box?)
Another interesting framework is Mojolicious, but it's interesting for being interesting, and also more complex than Dancer. One of its principles used to be, "what if you worked in a Perl shop but weren't allowed to use CPAN?" I would still steer a newbie to Dancer for webby things though.
BTW, Perl6 (which is a different language within the Perl family, but still interesting) will be officially announced at FOSDEM 2015. People have been running it for a few years now but there were some core optimisations and libraries they wanted added before calling it "out".
