Yes, it's correct.  In order to include a gem, you have to include
rubygems.  You don't necessarily need to use require_gem (plain require
should work so long as you've already require'd rubygems) but it can be
helpful to remember what's a gem and what isn't.

As for rails, you shouldn't need to include it explicitly.  I'm not sure
exactly how it all works internally, but if your database.yml is set up
to use mysql, it will automatically require the gem.  I believe that
Rails simply require's whatever the adapter string is, but again, I'm
not sure.

Sure!  Install it from source instead of as a gem ;)

Alternately, you could go into wherever you have Ruby installed
and write a little wrapper in a mysql.rb file that simply requires
rubygems and mysql.  I'm not really sure how that would work, though, as
I just tried it and it... didn't.

Really, though, it's not that bad to just require rubygems, is it?  ;)

Everyone starts somewhere :) The Ruby community is the nicest I've ever
known.  Bring your questions, they're always welcome and someone will
answer.
