The colour noise found in a high ISO direct digital capture has very different characteristics from high ISO colour film images so they really need to be tackled differently. In digital image capture NR as I generally shoot RAW I use the ACR Color Noise Reduction to reduce the colour noise but I generally set the Luminance Smoothing to zero and Sharpness between 0-5 since the third party filters seem to do a superior job on Luminance noise and sharpening before NR only tends to exacerbate the problem. I have a pre-set in NI which I start with, it's a little less harsh than the integrated pre-sets.
