Worked like a champ - one thing to keep in mind is that the room name cannot have a space character or it won't load into the address book and it wont even give you an error. Here is the script I created in case it can help someone else!
edit: YOU WILL NEED TO REBOOT THE TOUCHSCREENS AFTER YOU ADD THE ADDRESS BOOK - I ALSO FOUND THIS OUT THE HARD WAY!
