http://www.rubular.com/ is a great tool when working with regular expressions in Ruby as it visualizes the results instantly.

You could buy a book.
This is a great RegEx book - excellent reviews and has its examples in Ruby.
This is another great resource for testing your RegExs as you write them - but there is various software out there that can help you too (here and here)

You can also test your Regexp at http://www.rubyxp.com/
As peku mentions, instant visualization really helps.

The website www.regular-expressions.info contains a lot of information on regular expressions in many different programming languages, including Ruby.

+1 that site is a great resource. In addition to using that site, I would also strongly recommend reading a book on regex.Also, I use [The Regex Coach](http://weitz.de/regex-coach/) to test regex expressions.

Another good book is the Regular Expressions Cookbook: http://oreilly.com/catalog/9780596520694/

I personally find the book Mastering Regular Expressions by Jeffrey Friedl the best book for diving into regular expressions. Ruby's regular expressions are pretty much PCRE, but Ruby 1.9 also supports Oniguruma. It doesn't matter, know PCRE and you're good. The book will get you covered.
