Sintel Rig, tips on usage?

I’m assuming the Sintel.blend is the one I need to use, but upon opening it, well its kind of cluttered. I would really like to just use her for some animation tests, so bare-bones, low res is cool, all I need are the body and face (with mesh hair) controllers, kind of like the setup in William’s tutorial. Also tips on linking the needed parts would be great.
