    i guess you have to resize your map_canvas as well.

    so just add this to your resize()

    //its maybe better to attach this handler to the window instead of the document
$(window).resize(function(){
        $('#map_canvas').css("height",$(window).height());
        $('#map_canvas').css("width",$(window).width());
        google.maps.event.trigger(map, 'resize');
        map.setZoom( map.getZoom() );
   });

    so you have track of the resizing of your browserwindow 🙂
