Hi JT,
I am sorry that you have gotten this diagnosis. I know that it is tough. I think that you have gotten some great advice.
Regarding working with your HMO....I think that first you need to survey your thoughts and feelings regarding how to approach these tumors. Read about NF2. Check out the other resources that people have suggested. Then, you can formulate a plan for proceeding(which is what you really need when you have bilateral tumors). What are your priorities? I would like to suggest that you consider requesting an Auditory Brainstem Implant
http://www.earinstitute.org/news/facts/abifact.htm. This may be your way to get experienced NF2 doctors. I know that doctors Brackmann and Hitselberger work with HMOs and have traveled from House Ear Clinic in Los Angeles to perform surgeries all around the country.
As others have suggested, I recommend sending a copy of your films to House for their free consultation. Her is a link to consultation information. It is located near the bottom of the page

I know that this is all overwhelming and I am sorry.
Best wishes,
