Answer 1

Because the callback must be global, you could make one by accessing window from within the ready handler.

$(document).ready(function(){
   var s = document.createElement("script");
   s.type = "text/javascript";
   s.src  = "http://maps.google.com/maps/api/js?v=3&sensor=true&callback=gmap_draw";
   window.gmap_draw = function(){
       alert ("Callback code here");
   };
   $("head").append(s);  
});

Another option is to use Google Loader:

$.getScript('https://www.google.com/jsapi', function()
{
    google.load('maps', '3', { other_params: 'sensor=false', callback: function()
    {
        // Callback code here
    }});
});
