YAY! good for you, although that tut also shows you how to change a prop to a fig so you can constrain against it, usually in most cases you will be draping to a figure such as v4 or dawn, so you would skip the setup room bit.
If you look at the tut in the dynamics packs, I'm sure I talk about constraining. sometimes you might wanna add or remove areas on a piece of clothing and can be specific to a pose (eg making something fall off one shoulder but not the other)
