1) dogs have very sensitive noses. some of that stuff - like the taco - was pretty heavy. it's like getting kicked in the groin.
2) i'd be worried about the dog choking on a few of the smaller items. i've seen dogs that can barely eat out of a bowl without coughing.
3) your dog sucks. i've never had to teach a dog - especially not a golden - how to catch. it's innate.
regarding the carbs...
dogs are not obligate carnivores like most cats are. wild canids actually tend to eat a lot of fruit. you can pretty much follow the same rules as you'd follow for people - keep the refined sugars down.

You took it too far, it's not that serious. It's food, not bricks so his nose is probably fine.

no, i think you're underestimating how sensitive the nose is. that taco would have really stung, if she didn't move out of the way.
