1. If you form your own gang, you're the president. You can make changes and run the gang how you please.
2. If you join a gang, you might be able to find one that already has a lot of respect.
3. It kind of depends on the circumstances when you leave a gang but I haven't heard of a gang that attacks people that take off (that doesn't mean there aren't any).
4. From another thread I read. It sounds like if someone decides to strong arm you, it will just be for 10-15 respect and then they'll let you go.
