You won't see the hard copies in the computer as such but you should see them in the evidence part of the options panel. In terms of not being able to access your car, I can't imagine why as the wonders of Blade Runner is the freedom to take whichever path you want in the game.
All I can suggest is fire up the computer in Ray's aparment and click the picture that doesn't show the burglers and zoom in on the desk at the far end of the store and an item on it in order to maybe help you progress further. You might also want to zoom to the right of the big cage in the middle of the room as well.
hope this helps,
