Two newbie questions

Since you’re new, please do yourself a favor and learn Ruby first: has links to a few good tutorials (why’s poignant guide is odd, but can be useful).

Then, once you’re somewhat comfortable with Ruby, start learning Rails: is a great starter tutorial.

Also, if you can pick up books, look for the “Agile Development with Rails” and the “Pragmatic Programmers Guide to Ruby” books to get you started.
