I rented a D800E last week and used it for a shoot. I own a D700 too and use it all the time.
D800 is the same as the D700, go into the menu and adjust the timers to whatever you want for duration. You can adjust the exposure info to be on but it will suck up the battery. Review time is also set in the menu - you will have to do some looking since I don't remember if its in the shooting or set up menu but all the things you want to do are shown in the manual. Take 5 minutes and get the page number for the function, then go change it.
