Disable RollOut Function on Movieclips on Click Function

I'm doing a basic site with frame labels on the main timeline whose name corresponds to the btn names. A simple  otoAndPlay(evt.target.name);

I have a basic navigation setup of 7 mcs with mouse eventlisteners for CLICK, ROLL_OVER and ROLL_OUT.

Example:

prepare.addEventListener(MouseEvent.CLICK, navigate);
plans.addEventListener(MouseEvent.CLICK, navigate);
retire.addEventListener(MouseEvent.CLICK, navigate);
costs.addEventListener(MouseEvent.CLICK, navigate);
additional.addEventListener(MouseEvent.CLICK, navigate);
enrollment.addEventListener(MouseEvent.CLICK, navigate);
faq.addEventListener(MouseEvent.CLICK, navigate);

Here are my functions that coincide:

function navRollOver(evt:MouseEvent):void
     {

     evt.target.gotoAndStop(2); // each mc is setup to contain rollover art on frame 2
     }

function navRollOut(evt:MouseEvent):void
     {

     evt.target.gotoAndStop(1); // I'm telling mcs to go back to frame 1 where original art is
     }

// but now on the click function I want the rollover art to display static when that particular btn is clicked which is the same art that is on frame

     2 of these movieclips so I add the same method as under the rollover function

function navigate(evt:MouseEvent):void
     {

     evt.target.gotoAndStop(2) // But I'm seeing that the rollout function is conflicting with this

     gotoAndStop(evt.target.name);
     }

Does anyone know a better way to do this so when my mcs are clicked they display the rollover content/art? In essence I'm trying to achieve that when the user clicks a btn it goes to that "page" and the corresponding btn stays highlighted. Pretty standard web navigation technique but I just don't know what the best way to do this in flash is and with  how my site is setup.

Thank you
