It sounds like you're on the right track and gathering as much info as you can. Don't be surprised if you change your mind often as you learn about the options available to you. I started out wanting Gamma Knife, then it was surgery for awhile, then fsr, then back to GK again before I decided to go with radiosurgery via the Trilogy system. I think the process is sort of like deciding on a tattoo...you should be totally comfortable with your decision before you go through with it! Not that I have any tattoos, but that's what I've heard!
Good luck at Vanderbilt next week. Let us know how it goes!
