You should take a look at the rvm documentation which can be found at https://rvm.beginrescueend.com/

It's also useful to join the #rvm irc channel on freenode.net. There is a lot of (usually) real-time help for people during the week. It's probably a lot quieter on weekends.

That said, I *think* the way to set the default is like so:

  % rvm ruby-1.9.2-p290 --default

Of course, insert whatever the full name is of the Ruby runtime to set a different default (rubinius, jruby, etc).
