Beware, too much resizing causes it to get a funny shape referred to as the "kazoo" problem. MaleMedia is working on a morph package that will fix that, and give us some other important options as well. 

As to the other question -- well, any basement-dwelling nerd'll tell ya, boobs are waaaay more important than bippys. Guess the nerds in the Daz basement are no exception. ;-)
