You can use mudbox's or zbrush's built in normal map functions. Personally I put my high poly in max and generate the map using projection which I believe is a good work flow. Try to keep you're reliance on 3rd party applications/plug ins to a minimum unless you know for sure they're used within the industry.
I was pretty bored so I just mocked these up... My mate loves the Dragon type head but I done it in 40 mins and I told him it was a speed model that isn't really good in the 3D world xD The tech thing I normal mapped and everything in 10 mins (speed practice) EDIT: The tech thing was a test at mechanical stuff in zbrush.
