I have recently been trying out (and liking it so far) building web applications with catalyst. I have used the below module (Catalyst::Manual::Tutorial) which is very nice. I would try to learn the technologies used with Catalyst. Like Template::Toolkit, DBIx::Class. If you need help I would use irc.perl.org, and check out #catalyst, and #dbix-class, and #tt.
