Flash MX 2004 facing

I have a question. I have an idea for a game, and I’m still trying to figure out some actionscript stuff. I have two movieclips on the back ground that you move around seperately using WASD for one, and up, down, left, and right for the other. How can I make it so that they constantly face eachother? As in, no matter where I move those two MC’s on the screen, they continue to face eachother.

Also, if I wanted to have another movie clip that stayed between them, and stretched with whatever distance they are apart, how would I go about doing that? As in a string attached to each of them.

Feel like an idiot, but enh, any help or links to a tutorial on the subject would be appreciated. Thanks for the help, ahead of time.
