FS Racing for Dummies?

Hi, I recently finished a 10 hour sailing course on a Flying Scot and loved it. I had sailed before, but that was many years ago. Anyhow, I was wondering if anyone could point me to a basic book or website on dinghy racing. I'm looking for the rules of racing, typical racing setups, and generally tips for people who have never raced before but want to start. I won't be racing for a while. First I want to have several months of constant sailing under my belt. But as I get more experience on a FS, I'd like to mock practice racing and see if it's something I'd be interested/comfortable doing. Also, are there races out there for beginners? Or is it pretty much hardcore or nothing? Thanks!
