In Need of Help Bringing PS files to Flash

I am a Flash n00b. I am very good with Photoshop, but I need some advice from people who have used flash before. What is the best way to get a web layout from Photosho to Flash? Everything is in layers right now and there’s at least 50 layers so far. My next step in the design is to animate the site with flash. So, what would you suggest I do? Should I merge a few layers(layers that are able to be merged without ruining the design that is), or just import every single layer as is?

Thanks.
