OK thought of 2 more!

1.  When I open up V4 either in Daz or Poser... she has purple underwear, this can sometimes stick out from clothing... is there a way to make her nude?  I'm a girl, so it's OK I ask that.  :)

2a.  I opened the texture mat in PS... which brought up a question sort of unrelated... are these how people change the makeup for their characters?  If the answer to that is yes, I can alter these mats, save them and apply them to (in my case) V4?

2b.  The texture maps are sort of blurry, is there anyway to fix that?  Or is that just how it is when you zoom in to play around with them?

Thanks again for the help!

Oh and I will definitely check out the book.  I do feel a little weird about getting an older book but it sounds like it is a must read for what I hope to do.  :)  (Eeps just looked $50!)
