I erased all content on my itouch 8 gig and it now asks me to connect to i tunes now what

You should just reconnect to iTunes, and use iTunes to restore your content. If you don't sync your iPod and iTunes that often, then you will have to go back into the App Store, and iTunes and re-download your previously purchased content. Don't worry, they never charge you to download something you already paid for. The App Store has a great new feature when you go into the "purchases" menu, there is a list of everything you previously purchased that is not on the device. So, connect your iPod and allow it to set up and sync your device, and then go back to "purchases" in both iTunes, and the App Store, and you should be able to get everything back. If you're like me, and you sync your iPod at least once per week, you will have most of your content already backed up in ITunes, and replacing your content will be a breeze. Good luck.
