Answer 1

With brew this is a one-liner:

(assuming that you have tapped homebrew/versions, which can be done by running brew tap homebrew/versions)

brew install ruby193

Worked out of the box for me on OS X 10.8.4. Or if you want 2.0, you just brew install ruby

More generally, brew search ruby shows you the different repos available, and if you want to get really specific you can use brew versions ruby and checkout a specific version instead.
