Usually when drywall starts to swell - it's on it's last legs. It also usually gets softer at that point. The spots are probably mildew that needs to be washed off. If they can't be removed with bleach, then the drywall probably has mold and should be removed

Enamel paint and using a properly sized exhaust fan to remove the moisture is the best defense for protecting the drywall. If the ceiling cleans up and is fairly solid, a coat or two of latex enamel will help. A kitchen and bath paint would be even better. K&B paints are formulated for the harsher environment of kitchens and baths. They also have extra mildewcide.
