At the February 9, 2012, meeting of our user group, GGMUG, I gave a presentation on Beginning jQuery and jQuery UI. I had a great time and really appreciate all the folks who turned out to hear me rattling on.

jQuery.com (obvious) From here you can get to the other bits of the stack: jQueryUI, jQuery Pluggins and jQuery Mobile.
Pluralsight has 3 jQuery related video courses as of this writing.

The TekPub class is conducted in part by Dave Ward. Dave lives in the Atlanta area and is a real expert. You can follow his blog at Encosia.com. I highly recommend you check it out.
As for books I would recommend:
Hope this helps!
