So, you can go into the Material Room and replaced all the material zone's textures. 

I didn't touch the hair displacement map and I think that's my last obstacle.  The skin has all the wonderful textures, but the hair parts look a little flat and steal away some of the realism.

Jepe's Dick AM VI doesn't come with hair displacement maps, so for some reason, I'm feeling ambitous enough to think that I could create them myself using CS3.

We'll see.  The rest of my day is booked, so I'll try another time and let you all know how it goes.
