JQuery and Drupal book suggestions?

I'm launching a new site for work in a bit over a week that's built in Drupal and with JQuery used extensively. So far I'm pretty impressed with JQuery, especially how you can string things together. So I need to bone up on these two things, especially Drupal which I haven't had a chance to penetrate beyond the user interface bits.

So anyone got any book suggestions? For JQuery I'd want something that's reference-style rather than anything written as a tutorial. Drupal I need something that introduces me to the basic architecture, and then is more a reference. I've found I never really go through tech books that have tutorials and exercises and the like, hence my focus on reference material.

And since I'm asking for book advice, let me give some too. If you ever need to touch JavaScript, go and buy JavaScript: The Good Parts by JavaScript guru Douglas Crockford. It's quite thin (150 pages) and succinctly says what's good, and what's bad, about JavaScript. It's essentially a "work this way and you'll avoid most of the bad stuff about JavaScript" kind of book. Essential reading!
