Yep, a lot of these issues the OP reports can be resolved by, as a team, discussing how you communicate and what is a priority. That team seems to be lacking clear expectations. Oddly enough, that is a failure to communicate.
If someone does an @here or @channel or even an @person notify for a simple question that is not urgent, that is rude. Non-urgent issues should go in the channels and the person can respond when they get time, or e-mail it to indicate it's not a priority.
I really like Slack, but I do agree that it's easy to get carried away with notifications and integrations and it becomes a lot of noise. But most of these issues can be resolved by talking as a team about how the tools should be used.
