First and foremost, you are the best resource for learning Ruby. Lean by doing.
1) Work through http://ruby.learncodethehardway.org/book/ then work through it again.
2) Then pick up David A. Black's The Well Grounded Rubyist. Read it to fill in the blanks, then read it again to pick up the tidbits you missed the first go around.
3) Find other people. Look for guidance. Look for a mentor. Look for a users group (ruby brigade) in your area where you can find others to ask questions and advice on the topics that stump you the most.
Do this after working through Learn Ruby the Hard Way.
Mr. Neighborly's Humble Little Ruby Book is also a great intro to the language - http://humblelittlerubybook.com/book/html/index.html
I actually love the well grounded rubyist and definitely think all ruby devs should read it eventually but hesitate to recommend it to someone new to programming.
This has been asked over and over again. The last time I remember was 5 days ago. That's the best resource.
