I have to agree with everyone else here. If you send that email you are going to be looking for a new job pretty quick. It is a lot of information with good points mixed in with criticism. Because of this the focus is going to be placed on the negative of the email and is only going to frustrate the GM.
Learn to Manage your Manager.
From what I gather from your posting he is the type of person that wants all the decision making to be done by him. Changing his ways are going to be difficult. The key is to make your ideas his ideas. Be a sales person and sale each concept to him in pieces not all at once. Be positive about it and very careful not to criticize. Your Manager will come to respect your perspective on things and trust you to make the decisions. This is going to be a long process and will take a lot of commitment on your behalf.
The question is, are you willing to make that commitment?
Good Luck!
