Swim Breathing Technique?

Hi Everyone,
I'm new to swim training, and I'm having difficulty managing my breathe while swimming. I've read the articles on BT and have the Total Immersion book, but I was wondering if anyone could recommend other resources that discuss how to control and manage breathing, and perhaps have some drills to practice with?
I'm going to start masters swim classes in January, so I'm sure that will help, but I want to try and avoid starting any bad habits that I'll need to break myself of later on.
Thank you!
Jess
