I had a similar problem and posted about how I dealt with it here: http://geojason.info/2010/05/overlay-map-management-with-google-maps-api-v3/
Basically what I'm doing is inserting a null value for every overlay I plan on adding to the map into the map.overlayMapTypes array and then creating a new imageMapType when a check box is clicked. <http://geojason.info/2010/05/overlay-map-management-with-google-maps-api-v3/>Probably not the most elegant solution, but it seems to work.
