What is a fighting cut and what is a show cut? Please elaborate.
If the hood is open, the engine cools off faster

The reason ears help cool the dog is because there is more surface for the blood to expel heat. The vessels are close to the surface and the heat escapes very quickly. It has nothing to do with the ear hole itself being open since it is not the actual ear that gets rid of the heat. I prefer for my dogs not to have cropped ears bit I have owned a few with cropped ears.
Part of the reason people crop ears is, so when they get cut, they can't shake their head, flopping their ears around, and bust open the cuts over and over again. Deuce is the firs dog I have done however, so I don't have much experience with it, but so far so good.
I have never heard this either. If you ever have this problem just put some superglue on the backside of the ears and glue them together on the top of their head. Sometimes the hair on the back of the ears needs to be clipped for this to be effective. By the time the glue wears off the ears should be healed, if not just do the same thing again.
I have seen quite a few dogs that had cropped ears and have never seen or heard of one having problems due to the ears being cropped. I have on occasion heard of dogs having issues With their ears getting extremely dirty and or wet and causing problems with their hearing. I have also seen dogs that got so wound up when they heard the bay or got to the bay that they were a little disoriented and it took them a minute to get their wits about them and figure out what happened and where the bay/hog was at. It is like tunnel vision. Think about what happens when your in a stressful situation and get that adrenaline dump. Most of the time the people involved can't tell you what was said or any other details for that matter. You see what you are focused on and that is it.
