Answer 1

Simplest way is to create mouseover/mouseout event handlers for each marker to update the label text color.

// creates a marker with a closure for the event functions.
function createMarker(latLng, text, label) {
  var marker = new google.maps.Marker({
    position: latLng,
    map: map,
    label: {text: label, color: "white"}
  });
  google.maps.event.addListener(marker, "mouseover", function(evt) {
    var label = this.getLabel();
    label.color="black";
    this.setLabel(label);
  });
    google.maps.event.addListener(marker, "mouseout", function(evt) {
    var label = this.getLabel();
    label.color="white";
    this.setLabel(label);
  });
  return marker;
}
