Marg,
Welcome. I am a fairly new joineee to the group also.
I was diagnosed March of 2006, had surgery September of 2006. I am here to tell you that life goes on after your surgery, with some changes and adjustments. As long as you have studied your physician and feel comfortable, that's all you can do, is turn it over to them and let them heal you.
Before surgery, I had say 60% of my hearing in my AN ear. Pre-surgery, I had ringing in that ear, and typical muffled, seashell type hearing, especially in loud crowds. Pos-surgery, my hearing is arguably the same. The ringing is still there, and it has decreased a little, but I still have useful hearing in my AN ear, and you learn to adjust. I turn more to face people speaking with my good ear, I rely on my good ear more, put people sitting by my on my good ear side, and make other adjustments.
As for the balance, I am not a good one to speak to that. My doctor said that although they removed the balance nerve on that side during surgery, that I would hardly notice, cause my body had already gotten used to that side not having it because of the position of my AN. Pos-surgery, I had maybe a day or two that I was a little woozy, and had any noticeable balance issue. After that, I was walking normally, and fairly normal.
Best of luck. This forum is very helpful on all sorts of issues, so browse around, and feel free to ask if you have more questions, of myself or any member.
