I scan 4x5 at 4800 DPI on the 4990 (target: JPG), and then immediately downsize to 2400. (Photoshop > Image Size > 50% > Bilinear). The resulting 2400 DPI file is much cleaner than if you scan at 2400. I see zero image quality improvement by scanning at 16bit (as long as you do your color correction pre-scan), but a gigantic reduction in speed.
8x10 I scan at 2400 DPI. I'm not willing to wait for 4800 on 8x10, as the small improvement in noise is not worth the time. With a 16x20 lambda print, 8x10 is indistinguishable from 4x5 as scanned using my method... Though you can see it in the file.
