You'd need to loop through your overlays when you get an updated position and see if any of them are at the same spot and remove it. Just look at the current position and the position of the overlay.

To your other question: You will always have two LatLon pairs if you loop thru your overlays - the one from GPS and the one from your spot. Just use the static method Location.distanceBetween() to find the distance between these pairs. You can query every Location for it's accuracy in meters with getAccuracy(). Take these values into account.
