I strongly recommend: - jQuery (all the documentation you'll need is online) - O'Reilly JavaScript: The Definitive Guide - Firebug Javascript Debugger for Firefox. - Emacs Javascript Mode - Some virtual machine environment for IE6 testing (IE6 testing will be your biggest chore, but it's essential for any public website)

Also, read the source code of sites you like or to see how novel effects work.

This should be (almost) everything that you'll need.
