All good ideas. I'd include a few things:
A little note pad and a pencil to jot down all the things you forgot or want to do differently next time
A rangefinder, not to range specific animals, but to understand what actual distances look like in the woods
Surgical gloves for handling meat
10' of 1" nylon webbing for dragging the deer out
Headlamp in case he has to gut the deer in the dark
