There's another great Rails book available that is up-to-date with the new v1.2 release, Rails Cookbook from O'Reilly. I'm hoping to get it soon and will let you know what I think.
Lynda.com, purveyors of fine video-based training materials, have just released a new tutorial for Ruby on Rails. Totalling over ten hours, it seems to cover everything from the basics (installation) to slightly more advanced topics like dealing with multiple databases. Should be good!
I just discovered what could be the perfect tool for any self-respecting Ruby-on-Rails web developer: a RoR-based replacement for the venerable Trac that goes one better - it supports multiple projects/repositories out of the box! Simply perfect for my needs.
