Answer 1

I ended up solving this problem this way, adding the following code:

var clusterOptions = {
    zoomOnClick: false
}

markerCluster = new MarkerClusterer(map, markers, clusterOptions);

google.maps.event.addListener(markerCluster, 'clusterclick', function(cluster) {
if (map.getZoom() < map.maxZoom ){

    map.setCenter(cluster.center_);

    map.setZoom(map.getZoom() + 2);
} else {

    var content = '';
    // Convert the coordinates to an MVCObject
    var info = new google.maps.MVCObject;
    info.set('position', cluster.center_);
    //Get markers
    var marks_in_cluster = cluster.getMarkers();

    console.log(marks_in_cluster);

    for (var z = 0; z < marks_in_cluster.length; z++) {
        content = makeClusterInfo(marks_in_cluster,z); 
    }

    infowindow.close(); // closes previous open ifowindows
    infowindow.setContent(content); 
    infowindow.open(map, info);
    google.maps.event.addListener(map, 'zoom_changed', function() {
        infowindow.close()
    });
    } 
});
