Just keep in mind, learning Rails isn't going to be something you can do in just a couple or even a few months. To become good at it you'll have to practice day in and day out for years. But the good thing about it is, you will be able to deploy simple apps with minimal knowledge very soon which is fun!
My favorite tutorial thus far has been Michael Hartl's at http://ruby.railstutorial.org/ruby-on-rails-tutorial-book
It's long but it's very informative and walks you through rspec if you do decide to use that. Best of luck!
