I really love www.railscasts.com<p>While some of this stuff has changed over time due to changes in the Rails API, it's still a great resource to learn things you didn't even know you could do and to see how certain situations can be handled. Ryan does a great job making the screencasts short and very focused too, so you can always go there looking for something specific, and chances are Ryan has covered it.
A wise man once yelled at me after I badgered him with questions one too many times, "Use the source Luke". And that's what I'd recommend. Read as much Ruby source code as you can (ahem, github), make the effort to understand why the authors designed a piece of code the way the did. The Rails source continues to evolve into a great example of interesting to read Ruby - but you might want to start out with something a bit simpler like Sinatra :)
might not teach you ruby, but totally worth reading anyways.<p><a href="http://poignantguide.net/ruby/" rel="nofollow">http://poignantguide.net/ruby/</a>
