Success! Although it took a lot longer than it should, I finally figured out how to setup an AWS EC2 instance with Ruby on Rails pre-installed and setup, and ready! At first the AWS console looked forbidding, but once you stare at it for like 5 minutes, its not that different than setting up admin/user permissions on Windows. And I even setup the AWS command line interface.
While the online guide for AWS Console is a little convoluted, anyway I finally was able to get to my IP address for aftershoolio - my webapp that I plan to turn into a great dynamic and interactive website.
