First Flash website, any help would be great

Hey, I just started on my first real flash 8 website, www.hemjeans.com - they did this drop and bounce animation. I did the same type of deal using the timeline with a tween, but theirs looks so much smoother. Do you think they are using script for this?

Also, I want to use external .swf for my other pages but I’m not sure how to get a cool transition in and out.

I’ll take all the help I can get on this!

thanks
