Hi Darin Gallagher,
There are plenty of different ways to back up your tablet.
But really the simplest way to do it is using the software already installed on the tablet.
1- Google account
2- Samsung backup
3- Dropbox.
4- Kies
Google will restore your apps and your contacts, etc.
Samsung will restore your settings, etc.
Dropbox the best way to save your media, etc.
You can also use kies on your pc to back your stuff.
All the stuff stored on the external sd card is safe and will not be affected by the factory reset.
if your games are online? Than there shouldn't be any problem as the servers will remember the level you playing. But yes you might have a problem with offline games.
Sorry if my explanation is not clear enough,
But just look in the "settings / cloud / back up and restore" in your tablet and all should be explained.
