The noise reduction you have applied to this shot to remove the grain makes it look more smeared than it was before. I'm not convinced that applying more noise reduction to a source that has already suffered from noise reduction before is the way to go. It seems a bit like you're fighting fire with fire.
Don't forget that the excessive grain is part of the detail now, and in removing it you are inevitably softening the image further. If you were going to soften the image in this way, it would be nice if it were the result of anti-aliasing, but the aliasing still remains and the image looks less impressive. Your earlier, more subtle efforts were looking really impressive, though. I'd like to see those in motion to see how they look.
EDIT: Your post above looks much better, but beware of applying noise reduction to the GOUT. You will often end up with aritfacts and patches of grain on the image that can be far worse than just having the grain.
