I think mudbox is better at texturing then zbrush but that just might be me, I also use photoshop but you could just use mudbox. My work flow would be model the base mesh and UV in maya then send to mud, sub divide to the level you need then its a case of using projections and paint to get a texture(this is were I use photoshop to clean up the texture) and normal map that you can export to maya................dave
