Not really, to be honest. Practice, experience, and learn from your mistakes. ;) I just shoot when I can and pick up random knowledge here and there. It helps if you have a friend with more guns than you because they'll be willing to show them off.
As for the sound, I almost always go outdoors. Fresh air is better for your lungs and ears than an indoor range.
Get a suppressor. They can be expensive, but if they're legal in your state, look into it. They'll save your ears and make the concussion go away. Your shooting neighbors will appreciate it too.
Feel free to PM with any questions you might have.
I had glass floating in my beer once. I didn't notice until I drank some of it thinking it was small pieces of ice. It was in a country where I didn't speak the language so I had to find someone to explain to the bartender why I wanted a new beer.
When I was a kid I read Brian's Winter, part of the Hatchet series. He was scared by explosions while alone in the winter woods and found out in the end that they were exploding trees. Never forgot about that concept, but I never bothered to look up how big a tree can be and explode.
Ring doorbells now give their footage to Flock, which can give/sell it to anyone. No warrant necessary. Not exactly what you're asking about, but along the same lines.
He would find their attention to him endearing and repost it.
