Any way to remove the location info "bubble"?

It might not have liked having the empty function declaration.

GEvent.addListener(marker_0_0, 'click', function() {
marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
});

would become:
GEvent.addListener(marker_0_0, 'click', function() {
// marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
});

instead comment out the line before and after it as well like:

// GEvent.addListener(marker_0_0, 'click', function() {
// marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
// });

and comment just the one line before in the second example:

// if('address_0_0' == 'address_0_0')
// marker_0_0.openInfoWindowHtml(address_0_0.infowindowtext);
