How move main class to script in timeline

Question

hi , in some component they use main class to load various as files
and when i see properties of my document i see the name of this class right down the Script : Action Script 3
whe i click on the pen ( edit ) of this class i see various codes about doing importing some AS files and ...
for example :
package {
    import flash.display.MovieClip;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.net.URLRequest;
    import flash.net.URLLoader;
    import flash.events.*;
    import com.Align;
    public class DocumentClass extends MovieClip {
        private var ***;
        public var ***;
        public var ***;
        public function DocumentClass() {
        private function config():void {
sometimes i want to use 2 or more component that use this technics and i can only choose and type the name one of them !! 
how can i put them all together or it will be better if possible to put class in script in timeline ...

and here what i made at end :
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.events.TimerEvent;
import flash.utils.Timer;
import com.greensock.*;
import com.greensock.easing.*;
         var _sMouseOver:MovieClip;
         var _sMenu:MovieClip;
         var _menuTimer:Timer;
         var _menuOpen:Boolean = false;
        function MouseOverMenu():void {
            addEventListener(Event.ADDED_TO_STAGE, init, false, 0, true);
        function init(e:Event):void {
            _sMouseOver.buttonMode = true;
            _sMouseOver.addEventListener(MouseEvent.MOUSE_OVER, showMenu, false, 0, true);
            _sMouseOver.addEventListener(MouseEvent.MOUSE_OUT, startClose, false, 0, true);
            _sMouseOver.addEventListener(MouseEvent.MOUSE_OVER, cancelClose, false, 0, true);
            _menuTimer = new Timer( 50 );
            _menuTimer.addEventListener ( TimerEvent.TIMER, doCloseMenu );
            _sMenu.visible = false;
            _sMenu.alpha = 0;
            _sMenu.addEventListener(MouseEvent.MOUSE_OUT, startClose, false, 0, true);
            _sMenu.addEventListener(MouseEvent.MOUSE_OVER, cancelClose, false, 0, true);
         function showMenu(e:MouseEvent):void {
            _menuOpen = true;
            _sMenu.visible = true;
            TweenLite.to(_sMenu, .5, {y:73, alpha:1});
         function startClose ( e:Event ):void {
            //trace('startClose ' + e.target);
            _menuTimer.start();
         function cancelClose ( e:Event ):void {
            //trace('cancelClose ' + e.target);
            _menuTimer.stop();
         function doCloseMenu ( e:Event ) {
            closeMenu();
         function closeMenu ():void {
            if ( _menuOpen ) {
                TweenLite.to(_sMenu, .5, {y:50, alpha:0, onComplete: hideMenu});
            _menuTimer.stop();
            _menuOpen = false;
         function hideMenu():void {
            _sMenu.visible = false;
