Hey there friend! While I do not currently have time to answer all of these questions, many of the questions that you asked can be answered in a video that I made not too long ago. I’d encourage you to check it out as it has a lot of useful information for new managers/new teams. While everything that you asked is not covered in it, I’d say well over half of your questions will be answered. I’ll try to come back to this after I am off of work and give you some more pointers.
For now here is the video geared towards helping new managers and teams:
