Welcome to the forum! The D700 is a great camera isn't it? If you use Adobe RAW, Lightroom, or Apple's Aperature 2, the embedded JPEG file within the NEF RAW file, which is for previous purposes, will not match the converted NEF file unless the picture control settings on the camera were at default values. Many people forget this. Many third party RAW converters do reproduce Nikon's White balance settings with precision, so color might look a little off compared to an NEF file converted using Nikon's View NX or Capture NX.
When you modify a picture control and you are not happy with the results, the default setting of the LCD brightness could be an issue as well. Try -1 and remember the D700 like other Nikon DSLR are still not able to show the full spectrum of colors defined by Adobe RGB color space. Its actually closer to the narrow spectrum of SRGB.
With the contrast setting, if left to auto the D700 tends to add too much contrast I find. Remember its far easier to increase contrast than it is to reduce it. Therefore, it might be better to make adjustments in post processing.
