With your AN, your path is pretty clear. Surgery really is the only way to go. That simplifies things for you. I would, however, make sure that the people doing that surgery are the best there is. I think many of these surgical teams are tied for first place and there isn't necessarily one person who is "THE GUY" to have do it, but I think there are also many surgeons who rarely if ever do these operations and are more than glad to get you wheeled into the OR so they can go to work on you. My local guy was like that. I met him once, and he was all set to just dive in.
I decided to look around a bit. Duke Univ is only 1.5 hours away for me and they have an entire division devoted to brain surgery. It's all they do. Within that division are a handful of people that only do skull based tumors. They do them all the time and they are very good at it. So, my solution was to go with a team from Duke. For now, and hopefully many years, I'll be watching and waiting as mine is small. But, if and when the time comes, I'll be getting operated on by a team that does these all the time.
The point of my blathering is, I would take the time to see a few different Drs. to make sure you are getting the best people to do your surgery. This surgery is a big deal. It's not like some arthroscopic job on a tendon in your elbow. The results are usually good, the recovery is generally difficult, and the possible bad outcomes are truly bad. I don't think your 4 week goal of back to work is unreasonable, it's just that it could be 4 months. These surgeries are not a slam-dunk like your first post makes it out to be. It could be a walk in the park, but it's not a sure bet.
As close as you are to NYC, I would check out some of the world's finest medicine that is there for a second and third opinion.
