Pro JavaScript Design Patterns (Harmes/Diaz)is a really good book (that I think beat most of the list here to market).

Personally, I didn't care much for JavaScript The Good Parts, I just didn't find it that easy of a read.  I completely agree with What Andy Ford mentions about it being a book for those with a traditional CS background (not me).  I read it a couple times but just didn't get all the Crockford nut swinging around it...I admit I need to go back and re-read it and will at some point, but can't say I'm a big fan of it as others are.

I would definitely recommend the two books by Stoyan Stefanov:

Object-Oriented JavaScript
JavaScript Patterns
