I think you are still missing the point - the ONLY advantage to in camera settings is that someone at Canon or Nikon sat down and said something to the effect of, "Photographers routinely make these edits, so I'll build them into the camera." Convenient, but nothing that you can't replicate in Aperture, Lightroom, Photoshop, GIMP, or whatever.
While I actually dislike the look intensely, I would guess that the effect in the photos you linked is mostly a drop in saturation and maybe a kick up in contrast.
I agree that it is nice that Nikon offers things like Portrait, Vivid, etc., but one of the reasons I shoot RAW is so that I am NOT locked in as I would be with an out of camera JPEG that had already been de-saturated, sharpened, or whatever.
Scholars differ on this, but I would suggest that what you really want to do is learn the editing formulae to achieve any effect you want.
You can't really use Capture NX as an external editor as it is also a RAW developer. If you want to use Capture NX, either:
-- Run your images through Capture NX first and then import the TIFF into Aperture, or,
-- Take a look at Catapult: http://brushedpixel.com/
