You can also use the ArduinoISP sketch (File > Examples > ArduinoISP) to use one of your UNOs as an In-circuit System Programmer to burn a bootloader onto one of the new chips.
Be warned that the reduced serial buffer size in Arduino 1.0 has been causing many failures in ArduinoISP.

I believe that I read in the developers archives that they have fixed that for the upcoming 1.0.1 releasing sometime next month.
