Reparenting a movieclip already on the stage

Does anyone happen to know how to go about reparenting a movie clip that is already on the stage? I can only seem to find how to reparent sprites or children that were added. I’m working on a paper doll sort of game for a class http://comps.raemazing.com/tubbyWOOT.swf you can sort of get an idea from it here. As of right now it’s just adding a new child. Even if someone could tell me how to go about removing an old child that would be great. I’m sure it’s probably something simples… This is the code I have, sorry it’s so messy:

package
{
	import flash.events.MouseEvent;
	import flash.filters.DropShadowFilter;
	import flash.display.*;
	import flash.events.Event;
	
	public class Drag extends MovieClip
	{
		public var _targetPiece:*;
		public var _origX:Number;
		public var _origY:Number;
		public var _origXScale:Number;
		public var _origYScale:Number;
		public var _targetPieceX:Number;
		public var _targetPieceY:Number;
		
	
	
	
	public function Drag()
		{
			
			this.addEventListener(MouseEvent.MOUSE_DOWN, dragMovie);
			this.addEventListener(MouseEvent.MOUSE_UP, dropMovie);
			this.buttonMode = true;
			//this.addEventListener(MouseEvent.MOUSE_DOWN, createPiece);
		}
		
		/* function dragMovie(event:MouseEvent):void
		{		
			if(event.target == MovieClip) return;
			{   
			stage.addChild(this);
			event.target.startDrag();
			}
		}
		
		function dropMovie(event:MouseEvent):void 
		{
			event.target.stopDrag();
		}
		
	} */
	
		
		function createPiece(m:MouseEvent):void
		{	
			_origX = this.x;
			_origY = this.y;
			this.addEventListener (MouseEvent.MOUSE_DOWN, dragMovie, false, 0, true);
			this.addEventListener (MouseEvent.MOUSE_UP, dropMovie, false, 0, true);
		}
		
		
		function dragMovie(event:MouseEvent):void
		{
			stage.addChild(this);
			event.currentTarget.startDrag();
			this.filters = [new DropShadowFilter()];
		}
		
		function dropMovie(event:MouseEvent):void
		{
			event.currentTarget.stopDrag();
			this.filters = [];
		}
		
		
		/*private function dragMovie(event:MouseEvent):void
		{
			this.startDrag();
			this.filters = [new DropShadowFilter()];
			this.parent.addChild(this);
		}
		
		private function dropMovie(event:MouseEvent):void
		{
			this.stopDrag();
			this.filters = [];
		}
		
		public function disable():void
		{
			this.buttonMode = false;
			this.removeEventListener(MouseEvent.MOUSE_DOWN, dragMovie);
			this.removeEventListener(MouseEvent.MOUSE_UP, dropMovie);
		}
		 */
	}
