Help and guidance

We are trying to develop a website for a new idea of ours. We have been evaluating drupal and asp.net so far as a platform. And then we were referred to ruby on rails. I shall briefly highlight my background in programming. I will greatly appreciate if people can direct me to relevant material specially for beginners which rapidly help me evaluate this platform.

--- C/C++ highly proficient (BS and PhD in computer science) --- NO experience in web development whatsoever

Thanks
