I have just finished reading The Definitive Guide to Catalyst - Diment and Trout (Apress). As Catalyst Newbie, all I can say is buy and read this book.
It has lots of helpful advice and guidance, from creating your first application to extending Catalyst, and lots in between.
It also takes a good look at DBIx::Class, Moose and the Reaction framework, plus a good explanation of the MVC pattern.
I think this book is going to prove a valuable addition to our teams bookshelf, and be referenced for some time to come.
