Adam, my suggestion would be to use a hard wired lavalier microphone ‘subject 3-5 feet away from camera’. If there is a Radio Shack near you, they have one for less than $30.00. This could be later used with a portable recorder lke the Zoom H2. Suggestion number 2 would be to sound dampen the surroundings in the room (if this is possible?). This would save the work involved in post. Monitoring the audio (headphones connected to camera) should give you a headsup while recording. Keep shooting.
