Shameless plug: I collected a bunch of resources for learning Ruby, Rails, and general programming on Rake Routes a couple months ago: http://rakeroutes.com/blog/learning-ruby-rails-and-programmi...

On the article, I strongly disagree that vim requires plugins to be viable for Ruby development. The Janus plugin should especially be carefully considered as it wraps up a lot of magic that could prevent the new vim user from effectively learning vim itself.
