You can open the NEF images in Veiw NX and let the Nikon software apply the camera settings. Then from the file menu you use 'Open with ...' to directly transfer a memory TIFF image to LightRoom or other appliction.
Adobe is working on an ACR/DNG profile editor and camera profiles. There are Beta, end user testing version, versions available through Adobe Labs.
