Is there any recommended maintenance, other than the cabin air filter, for the Air Conditioner on a 2002 DuraMax?

Keep the condenser clean (heat exchanger up with the radiator in the cooling stack) and check for leaks and compressor bearing failure. Leaks are shown at any fitting that has oily dirt stuck to it. Mechanics stethascope makes it fairly easy to determine if your losing a bearing.
