I just loaded Windows 7 x64 to a Dell Latitude D830 and it's working great, but the Windows Experience score is 3.3 on the Aero video performance. The next lowest score is 4.9, so the video performance is dragging the score down quite a bit. I've heard it should be better than that with the NVidia mobile Quadro NV140M card that's in there. I loaded the 64-bit drivers directly from NVidia's site. Am I missing something?

Your not missing anything at all. The Windows Experience score is quite strict in what it expects to calculate score. Unless you have some sort of indication of what the score is you would like to see, the actual score is fairly meaningless.
It is rare for me to see a graphics card give more then a 4.0 score in a notebook, unless your running an Alienware top of the range SLI.
IMHO The score is an indication but by no means a perfect indication of how well the card will perform. I have also seen a card's score drop between x86 and x64 installations. Unless your building this machine for high end gaming there should be no need to get the score higher, as it is more then sufficient to run day to day applications.
