Answer 1

You might consider using the Rails Installer for windows if you can use Ruby 1.8.7. It will install ruby and rails and other dependencies for you. There are screencasts and other help as well.

If you need ruby 1.9.2+, then it looks like you might be out of luck unless you upgrade to ruby 1.9.3. You can read about it here.

Good luck!
