If you haven't updated to iOS 5 yet, make sure you sync your device first by clicking on the device in the left-hand column of iTunes, then hitting the "Sync" button in the bottom right corner. That way, no matter what happens during installation, you'll still have everything backed up.

Once again, be patient. Lots of people are trying to download and install iOS5 now, and if you unplug your device too soon, it may only cost you more time undoing mistakes. I'm saying this from experience.
