navigation loading movieclip wrong

Wow, well, I am not completely new to Flash, but am not real experienced. I more or less know how to create animations with it, with a pre-loader if necessary. I am now working on my first full flash website & am trying to create the navigation. That said, I can't quite get it to work correctly. This actionscript stuff is frustrating me. I want to get it so that when you roll over one of the buttons, it plays a small animation that flashes on top of the button. I seem to be close, but can't quite get it to work correctly.

I have attached the file I have so far. The first 2 buttons have animation attached. The first one I thought worked, but it seems to not work on the first time you roll over it. The second one, just keeps on repeating when you hold the mouse over the button. I would like it to just animate once each time the mouse is over it. Hopefully that makes sense. Any help would be awesome & if you could explain what the heck I am doing wrong for future reference...even better. Thanks!!

im not sure if you still need this but i have fixed your glint problem, there was an invisivle script in the last frame that kept telling it to replay.. i deleted the last frame and then re-made it here it is
