This is from professional experience:
1. Shooting raw only (NEF)
2. Tone compensation: Less contrast
3. Sharpening: Low
4. WB: Cloudy
All others vary, like spot/matrix or center weight metering, AF assist light (usually on), ISO (try lowest feasible), Mirror lock, Noise Reduction (on with slow exposure)
Never use red-eye reduction on the flash (makes people squint), fill-in flash using slow-sync (if low light using a tripod)
I found out that WB cloudy is usually good, except when using flash, but anyway with Nikon capture it can be tweaked to a single digit Kelvin temp. without any artifacts added to the image. The correct exposure and the focus are still very important to get when you shoot. Eventhough you can correct exposure, usually if you correct more than .3 EV , you will get unwanted artifacts (noise) added. If you nailed the exposure and the focus, you would get a superb image.
After shooting you normally have to sharpen to your taste and increase contrast accordingly. Noise reduction in NC is practically worthless, get other tools (PS actions , NeatImage or others)
