This might be overkill for you, but at a certain point I just set down for a few days and read The Rails 3 Way front to cover. It's a reference of sorts and it's very complete (afaik). I marked all the things I hadn't known or thought was interesting and made a point of using then right away. It was really dry at times but turned out to be well worth it.
