Olle Rydberg has a nice tutorial/overview of the Maya-ZBrush workflow here. He gives a concise breakdown of the base mesh, mapping, and rendering phases with a very useful description of the various render passes. Interestin'! BTW, SSS = SubSurface Scattering!
Below are a few pictures from a model I started recently. I made the base mesh in Maya, and then kicked it around for about 30 minutes in ZBrush.
