You may want to look into an NRA Basic Shotgun class. You get both parts you mention above, & will leave knowing more about shotguns than most people.
Maybe check nrainstructors.com & kelkye.com to start.
Thanks for the advice, I will check them out. I've taken both the NRA Basic Handgun and Rifle classes and if the NRA Basic Shotgun course is as good, then I know I (and everyone else!) will be safe when I go to the range. I don't have any family members who shoot, so I've had no "elder brother/cousin/Dad/Uncle" to show me the ropes. The NRA classes have been my best buddies!
