What sound effect should I put at these parts in the scene?

For my sound class I need to take a part of a movie that I like and redo the sound. So I have to put some sound effects in there and a whole new background music.

The movie I chose was The Breakfast Club and the scene that I took was the ending. This part: http://youtu.be/mWUhcKUYbT0

Right now I’m busy putting in some sound effects and I wanted to put a sound effect at 0:22 where Andrew and Allison kiss and at the end where Bender raises his fist.
What sound effect should I put here?

Also I’m searching for a song for the background music, any suggestions?

This is to change the whole feel of the scene.
