jQuery
A JavaScript utility library so useful and important that most of the major websites in the world now include it, and most major JavaScript projects build on top of it. If you're not already familiar with it, take an hour or two right now to fix that. I'm no fan of Microsoft, but the best videos for newcomers to jQuery I've seen are chapters 14-17 of this series. Go watch them.

Update: I was wrong! The core team have been using jQuery 1.8 on master without problems. Thanks to Luke Melia for answering my comment, and Ember Noob reader Sylvain Mina for catching the error.
The Framework
The three pieces of the framework are Ember, Ember-Data, and Handlebars.
