Google Maps V3 API for Codeigniter [Adding Numbered Markers + other questions]

I have several questions regarding the Google Map V3 API and its library for Codeigniter which wraps the PHP class for google maps api.

1. How can I have the marker show A,B,C… or 1,2,3…? (most important)

2. How do I prevent the white bubble box from opening up when I click on the marker?

3. After adding a marker using addMarkerByAddress() inside my controller, is there any function that I can call from within the controller to remove the marker? Because after a开发者_JAVA技巧dding directions to it, the marker from addMarkerByAddress() overlaps with the start/end marker in my case so I need to remove the initial marker.

4. I cannot seem to have the map display without calling addMarkerByAddress(), is that right?

This has been bothering me for days so I hope someone can help me out!!

For showing custom markers use this:

var latlon2 = new google.maps.LatLng(44.959944, 26.0186218);
marker2 = new google.maps.Marker({  
            position: latlon2,  
            map: map,  
            icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=A|FF0000|000000' 
            });
