Before you do that, you need to open each tab and answer the questions carefully. Since we aren't concerned with contacts it would probably be ok to hit apply and let it sync, but better to be safe than sorry. In the photos tab, you will need to select your albums, you will also need to select the vids to sync. When you get through with all the tabs, you will need to do your apps again, because if you don't hit apply it will put them back like they were. Sorry bout that, but I forgot. Onece you are done with the apps, hit apply and it should backup and sync. I usually sync it again just to make sure. I'm gonna be up awhile, let me know how it goes.
