check out www.ruby-lang.org/en/about/
something that may be helpful for you to understand is that Ruby is the
language (created by Yukihiro "matz" Matsumoto - www.ruby-lang.org)
and that Rails is a web application framework (extracted from the
Basecamp project by David Heinemeier Hansson at 37 Signals) that
utilizes that language.
I, also, am quite new and would recommend the book "Agile Web

http://www.pragmaticprogrammer.com/titles/rails/index.html - to help
you get started.
