I think everyone has given you great advice. I'll just throw another contender into the mix. BFG just released their Mud Terrain TA/KM2. I am dying to try them, but I presently have too much tread to justify it. They are supposed to be great off road. I don't know how quiet they are. A few people here have already tried them (like H2Rocks). You might ask her about them.
