The goose should be gutted in the field, all internals should be removed well before he pulls into your driveway at the end of the day. If hes not willing to take care of the meat he shouldn't shoot it in the 1st place.
As for the feathers a plucked bird will make the nicest meal, but its an awfull lot of work and many people simply carve out the breast, but check your local regs, here in Ontario only taking the breast is considered wasting game meat and is illegal.
