First use the LOJ tool "Make GPX file" . I haven't experimented enough to know how many waypoints this will handle. Any GPX file will work. In Google Maps on your PC go to "my Maps", create new map, import. It will say you can only import KML, and RSS something, but it will import a GPX. Title the map.
On your Droid, open Maps, go to Layers, more layers, my maps. Your saved map will be there with the waypoints, you have to touch them to get the label.
