Crockford's "Javascript: the Good Parts" is what you want. It's short, well-written and introduces a lot of ideas that get you thinking about js on a higher level. It was actually a pretty influential book in getting people to start respecting javascript as a proper language in its own right. I'd also recommend javascript weekly for articles and news to keep you on the cutting edge.
