Render settings are always going to be project specific. When I looked at the mov file I didn't see any glaring issues. If your going to composite then use the best image format available to you. Personally I would swap from png to tif format. Tifs are much much bigger in size and you seem to have a rig that can handle it. Render times will increase also so be prepared to leave the system alone to render. It's going to be trial and error but once your happy dump a screen shot here and we can have look and see what's going on. Motion blur is up to you, but don't over use it or make it appear to strong, with motion blur subtle is best IMHO.
