The safe answer is to use an existing property of a Marker. I'd
suggest Title since it doesn't really have a user-interface impact.
The other answer is that it's totally possible to add a new property
to markers to keep track of that. Something like:

google.maps.Marker.prototype.MyUniquePropertyName = 0;

However, this should come with a disclaimer: API updates can break
your map. Make sure that your property name does not conflict with
anything used in the Marker class - in fact I recommend naming it
something you know that Google will never use.

Same answer as number 1. Keep an array of Markers that you add, then
loop through the array calling setMap(null);
