Apple probably won't show it as shipped until tomorrow. Use your billing phone number as the reference number on the UPS and FedEx tracking sites. Apple shows "preparing to ship" on mine as well, but UPS shows it in Kentucky.
Just use the 10 digit number without dashes and be sure to add in the country, zip code and shipment date estimate. But if it said 11/2 delivery and it isn't showing up on the tracking websites, I wouldn't worry about. You'll get your shipment email tomorrow.
