Regarding the smell -- I was on a site the other day that had some sort of service bulletin related to a "musty" smell coming from the climate control system. I'm not a subscriber to the site, so don't know the details, but the link is titled "A/C - Musty Odors From Heater and A/C Systems". Looks like it may be a known problem, anyway:
