For what its worth, you may want to consider using EPA's WMS for some of your visualization, especially when you either start displaying a lot of points, or start to get to polygons. (GeoXML will work, but nothing seems to run at a tolerable speed when displaying 100 or so assessors parcels as polygons... as images, however, its all good. Presumably wetlands files will get similarly painful). MassGIS has a very nice and detailed tutorialwalkthrough about googlemaps and WMS on their website. http://lyceum.massgis.state.ma.us/wiki/doku.php?id=googlemaps:home
For data queries, you can use WMS GetFeatureInfo, or if you find this to be too slow, start using limited WFS queries with Lance's GeoXML to load and even preload bitesized blocks of data.
