I think I might be able to add something to this discussion, since I AM an orthopedic surgeon, but I would also add some general cautions about "Internet advice"
Every patient is a little different....some things that are highly relevant, but have not been discussed are : Is the injured shoulder your dominant one?
How old are you?
Do you smoke?
Do you have medical problems?
I am not suggesting you answer these in a public forum, but with all due respect to the advice offered thus far.....the answers to these and other questions are EXTREMELY relevant to whether or not surgery is or is not a good option.
I should say first that I tend to be generally conservative, and in almost all cases I agree that trying physical therapy first is the proper course. There are, however, cases where PT will NOT be effective, and will only delay the course of recovery.
I also would agree that you should seek out an orthopedist who does a good amount of shoulder surgery and who has a good reputation with the local PTs - explain your symptoms, your concerns and your expectations up front and don't be afraid to ask questions !!!
Even if I were to see your MRI on-line, I would still not give you more than this general advice, because a good physical exam and a face to face discussion is crucial to good patient care ! I would be happy to translate "orthopedic-speak" if you have questions in that regard though - either here of thru PM or whatever.
