I'm pretty sure Daz3d.com has various tutorials. Plus there were several .pdf that give you hints and tips. Though I haven't got to study them. Note that a great helping guide doesn't come with the dload, but you have to search for it in their site(as I have it it must be there).
But I'd closely monitor the PC mags that come with dvd's. Since it's already ver6, ver4 will be available sooner or later for non profit purposes with one of them.
