need help creating a loop

so i have the .mp3 and .gif ready for looping with Adobe Flash Pro and few things i can't accomplish:
-i can't import .mp3 to stage
-i can't make a text appears when hover mouse over it
-i don't know how to upload the .FLA to the site
i'm a beginner at this stuff and soryy if i'm asking for too much

1. Sound
   • Drag'n'Drop the .mp3 into your Lib.
     
   • Click at the frame, at wich the music should start looping,
     
   • Go to the "settings window"
     • >Name: Choose you audio file
       
     • >Effect: doesn't needed
       
     • >Synchro: 'Start', 'Loop'
       
   
   
   
2. Mouseover
   • Make a new layer and fill it out with black color.
     • Convert it into a movieclip.
       
   • Doubleclick the movieclip. Settings -> instancename (name it )
     
   • Set the alpha of the movieclip to zero
     
   • Make a new layer while you are in the movieclip and use the texttool to write some shit.
     • convert the text into a movieclip. (And also give it a name)
       
   • copypaste the following code:
     
     Code:

     mouseover_mc.addEventListener(MouseEvent.MOUSE_OVER, show_info);
mouseover_mc.addEventListener(MouseEvent.MOUSE_OUT, show_info);

function show_info(e:MouseEvent) {
    switch(e.type) {
        case MouseEvent.MOUSE_OVER:
            text_mc.alpha=1.0;
            break;
        case MouseEvent.MOUSE_OUT:
            text_mc.alpha=0.0;
    }
}
     (Replace mouseover_mc and text_mc with your movieclipnames)
     
   
   
   
   
   
   
   
3. Publish
   press 'ctrl'+'enter' to publish your flash. There will be a .swf file next to your FLA.
   You can upload your loop here: http://z0r.de/up/index.php
