ActionScript 3.0 :: Flash On Button Rollover Dynamic Text And Movieclip Appear?

When one of my buttons is rolled over, I want text and a movieclip to appear. When the button is no longer rolled over, I want the text and movieclip to disappear.The way that I was going to do this was to have anchor_mc as an anchor, and upon rollover have the movieclip play from inside the anchor (as its at the exact X & Y that its needed at) and dynamic text appear.

1) Is there an alternative way of doing the below, to avoid so many listeners?

2) Can the below functions be merged into one?I've tried merging them into one using IF statements, for example:

if(event.target.name == line1)
{
line_output.text = "This is a test made by the MonkeyTest that has previously messed up
And testing a new line";
gotoAndStop(2);
}

However this does not work, and gives an error.

3) I had to get the background to display by moving to the next frame. I could not work out how to get the textbox to appear at a specific XY, or how to get the textbox to disappear after a rollover. Is there a better way to do this, or is what I'm doing acceptable? (NOTE: Textbox is a Movieclip)

AS3 code is attached below.

Code:
import flash.events.MouseEvent;
stop();
