For the noise problem I would say as long as your going to carry a lot of things a small pair of make up scissors may work or I used to carry a razor blade in my wallet back in the day. I only took it out when I would go through metal detectors at the airport or court. I even forgot it once or twice and they didn't go off. I was also thinking covering the wrapper in masking tape might help quite them. Please post your plans when you get them together, I'm sure they may help someone.
