Contact PANC CBP directly, they can help you make the arrangements in PADK. As I recall they will arrange to send an officer there to meet your flight, just be sure to keep them updated with your ETA.
The fueler / handler is easy to arrange there on your own. All it takes is a phone call. Be prepared to place all charges on a credit card. They can also give you some information regarding the US CBP arrangements there.
