Oh, I forgot synching..
To copy your personal calendar to google, use their new synch tool...
..and then uninstall it.
It crashed my wife's Outlook 2003 almost every hour when it synched up, and I'm still finding strange entries in my Deleted Items folder in Outlook 2007 from when it was running - every hour it would create a few dozen empty appointments from 1979..
If like me you decide just to move over, then it's no problem. Just let it synch once, and uninstall. But if you're trying to sit on the fence then be aware there are issues with this tool.
