This is the best Online Reading material i found out regarding rails 2.x. Try this out, it may help you....
Hi, I'm not into paper either :)
I'm not sure that's what your looking for but you might want to take a look here: http://envycasts.com/products/ruby-on-rails-22-package-deal
It's a PDF book and/or screencast about the new stuff on Rails 2.2. It's not expensive and there are some demos so you can take a look at what you're buying.
I'll warn you that's not a Rails Way updated, but if get the basics and the philosophy from the original one you just need to upgrade the tools. I hope it helps.
