I've been meaning to post a crystal popping/installing tutorial (using a crystal press), and one of these days I might actually get around to it.
Tools:
Get good ones. I like to refer people to the timezone beginner's class where they have a basic tool kit. Don't buy the kit, unless you want the movement that comes with it. But, use the kit components as a reference for which tools to buy, and buy the ones you want/need individually.
Lots of additional info is available via search, as well.
