Before you restore the iPod make sure that your iTunes library has the version of apps that are presently installed on your iPod. Many apps have been update and the update apps are not compatible with the 2G iPod. I would do that by deleting the apps from your iTunes library and then transfer them to iTunes. See:
In iTunes 11 use Control+B to show the Menu bar then go to iTunes>File>Devices>Transfer Purchases
