I'm pretty forgiving of most behavior at concerts.
The things I really dont like:
- People who try and ruin other people's fun by telling them to sit down or be quiet or stop dancing or whatever. If you dont like that shit, go stand in the back and let others enjoy the damn show like they want you miserable bastard.
- People who throw things. "Hey here's a shoe on the ground. I should throw this." C'mon.
- People that get super drunk. Its ok if you're drunk, having a good time, whatever. But if you can barely stand up straight or are puking or something, its time for you to go sit down or leave or something.
So yea, only 2 of the things listed in the OP really bother me. The rest, I dont care for the most part. It doesn't affect me if you're filming the show or taking pictures with your phone. I dont care if you shout out requests or 'Freebird' or anything, even though its pretty pointless. Its just kind of concert tradition and people are really excited to hear their favorite songs. People talking to friends - its a concert! Its a music show, but also a huge social gathering at the same time. Its not like you can usually hear people talking that much anyways while music is playing.
