2 other options:
Just have one event handler per button.
or use an anonymous function
myButton.addEventListener(MouseEvent.CLICK, function(){doSomething
(1);});
private function doSomething(index:int):void
{
trace(index);
}
(I havent tested the code above, so there might be some syntax errors).
Personally, I would always have one event listener per button as I
feel it make it a little easier to read the code.

One way would be to create a subclass of Event that stores the
parameters.
In this case, though, I wouldn't even do that. You can just use
event.target to determine which button was pressed:
function onPressed(event:Event):void {
var button:Button = Button(event.target);
// Do stuff with button.
}
If you need to specifically use an index number, I'd attach that to
the
button instances themselves. Then you could retrieve that via
event.target.
