You can use a loop to attach the event listeners to the buttons:

for (var i:int = 1; i <= 64; i++) {
    this['b' + i].addEventListener(MouseEvent.CLICK, btnClick);
}

And use a single listener function:

function btnClick(event:MouseEvent):void {
    trace(event.currentTarget + ' was clicked.');
}
