The process is the same as if you are upgrading from a 3G to a 3GS. You just run a backup on the existing phone, and when you plug in the new phone to sync for the first time, you should get a pop up window that says a backup was found for a different device (the 3G, or 16GB, in your case). It will ask you if you want to use the backup to restore data on your device.
Although, it may ask you to update the software for the phone first, as in 3.1, if the new phone doesn't have the upgrade, yet. I guess it depends when the store actually received the device, it could have 3.0, 3.0.1, or 3.1 on it. Everyone may also want to know if you are going to be able to use MMS on the phone right out of the box. It would mean that AT&T is serious about the 25th.
