With depth of field I notice the objects
that are not in crisp focus appear to be
grainy instead of a smooth blur. What cures
this problem? Is it the aperture, is it the
focus distance? I would love to get clean
clear blurs at render time using depth of field
with Mental Ray.

You need to increase the antialiasing quality. You'll probably have to increase the samples and lower the colour thresholds in the render globals.
