A possibly easier way to get what you want would be to use a skin that allows you to hide the settings menu (Conq, ReFocus Big Light are ones that I personally know of) and set things to kiosk mode. There are ways to get to the settings if you need to but your family won't be able to muck around.
It might not be the solution you are looking for but there is no messing around with .xml files this way.
