Streamlining the code for the button group with individual links and rollover imgs

Question

I am looking for a solution to streamline the code for the array of 20+  buttons located inside the scroll pane.
I know I can make an array if all the buttons would have a unified code executable change, i.e. they would become larger and brighter.
My problem is that each button represents an product image in the lights off stage, then of rollover it is a lights on stage so I have to import two images in the on and off stage and play around with the opacity.
Additional problem is that each button has to ling to a different label.
My question is: is it possible to unify the code if buttons have that much individuality or I have to make each one of them as in the example below.
// makes a hand cursor appear over a mc acting as a button for all the buttons inside the scrollpnaeBckgrnd_mc.scrollpaneBckgrnd_btns_mc.
MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.buttonMode = true;
MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.useHandCursor = true;
///////////////INDIVIDUAL BUTTONS
          MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.FloraLyte _btn.FloraLyte_ON.alpha = 0;
                    var  FloraLyte_btn_Tween:TweenLite = TweenLite.to(MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.F loraLyte_btn.FloraLyte_ON, .5, {alpha:1, paused:true});
                    MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.Flor aLyte_btn.addEventListener(MouseEvent.ROLL_OVER, overHandler_FloraLyte_btn);
                    MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.Flor aLyte_btn.addEventListener(MouseEvent.ROLL_OUT, outHandler_FloraLyte_btn);
        MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.FloraLyte_btn. addEventListener(MouseEvent.CLICK, onClick_floralytePopUp);
                  function onClick_floralytePopUp(event:MouseEvent) :void {
                                        gotoAndPlay("floralytepp");
function overHandler_FloraLyte_btn(e:MouseEvent):void{
         FloraLyte_btn_Tween.play();
         trace("you rolled over me");
function outHandler_FloraLyte_btn(e:MouseEvent):void{
         FloraLyte_btn_Tween.reverse();
         trace("you rolled off me");
MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.FloraLytell_btn .FloraLytell_ON.alpha = 0;
                    var  myTween:TweenLite = TweenLite.to(MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.F loraLytell_btn.FloraLytell_ON, .5, {alpha:1, paused:true});
                    MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.Flor aLytell_btn.addEventListener(MouseEvent.ROLL_OVER, overHandler);
                    MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.Flor aLytell_btn.addEventListener(MouseEvent.ROLL_OUT, outHandler);
        MovieClip(mc_pane2.content).scrollpaneBckgrnd_mc.scrollpaneBckgrnd_btns_mc.FloraLytell_bt n.addEventListener(MouseEvent.CLICK, onClick_floralytellPopUp);
                  function onClick_floralytellPopUp(event:MouseEvent) :void {
                                        gotoAndPlay("floralyte2pp");
          function overHandler(e:MouseEvent):void{
         myTween.play();
         trace("you rolled over me");
          function outHandler(e:MouseEvent):void{
         myTween.reverse();
         trace("you rolled off me");

Answer 1

as ned suggested, plan your flow and code into it. here is one example:
var buttonArray = [someButton, someOtherButton, aDifferentButton];
for(var i = 0; i < buttonArray.length; i++){
     //get reference to county movieclip
     var mc = buttonArray[i];
     //then add listeners
     mc.addEventListener(MouseEvent.ROLL_OVER, overMe);
function overMe(e:MouseEvent){
     var mc = e.target;
     switch(mc){
          case: someButton:
                   someOtherButton:   doThis();
                                                 break;
          case: aDifferentButton:     doThat();
                                                 break;
          default:                            //do nothing;
                                                 break;
function doThis(){
     trace("do this")
function doThat(){
     trace("do that")
