Chris; Thanks so much for the spreadsheet. It helped me plan the setup of my D800 Christmas Present. My experience with the D300 version of your spreadsheet sped things up a lot.
Here's a modest suggestion regarding the Extended Menu Banks option, I added a line immediately below the Extended Menu Banks line (Shooting Menu:12) called Extended Menu exposure mode. For each of the four banks I noted the exposure mode and intended default value for shutter speed or/and aperture (the user manual page reference is of course n/a). This lets me maintain configuration control of the default values stored.
As you've noted elsewhere, keeping a copy of the .bin file on a small SD card stored in my bag always lets me get back to ground truth after I screw up. The fact that the D300 file is named differently than the D800 allows both .bin files to live on the same reference SD card so I only have to carry one to serve both bodies.
