An 8' copper grounding rod should be pounded down into the ground right next to the building, and all the ground and neutral wiring should be connected directly to that local earth ground.
If the circuit comes from an existing circuit breaker panel that already has a service disconnect then bonding grounds and nuetrals here may be a code violation. I don't have my book here now to double check but I think there is an issue.
As for driving a rod? Yes sir to that and a UPs. Also, you can bury a rod horizontally as well as drive it.
