Wups! I forgot all about this after a evening of tweaking your scene
file and didn't get back about this. I found the max_trace_level to be
relatively unimportant. Using the defaults for 'radiosity' seemed to be
about as good as anything else I tried. Think the unsmooth metal texture
you were getting is just about impossible to get rid of, at least
nothing I did completely fixed it up. Upping the 'grey_threshold' to 1
helps but removes the nice blending of gold and steel colors it had.
Glad you were able to help yourself.
