The IF Life
Mike has a good introductory post on how to start IF and also a collection of studies (a few of which are also scattered around this blog) on a useful resources page. It looks like it will be worh keeping an eye on his writings.
If you want to read a bit more on the subject, I think that Fast 5 and East Stop Eat remain great introductions to the science and practice of IF.
