I've been using the Nikon 9000 for many years with Nikon Scan. It works fine. I try to get the maximum scan information without any processing while scanning. For "keeper" images, this means 16 bit tiff, which Nikon Scan does well. Post processing then takes place later in Lightroom or Photoshop. I also own Vuescan, but don't use it with the 9000. I don't understand what problems have with b&w scanning. I use it a lot, in fact predominantly. You need to have the ICE turned off for silver based films.
One quirk is that you need to make sure the 35mm strip film holder in securely closed before insertion. Otherwise it may jam in the mechanism. If this happens, you need to disconnect the 9000, turn it upside down, and remove the many screws holding the cover. Then remove the cover, close the holder, and put everything back together again.
