Emulating image maps

First off I am a newbie to flash so please bear with the questions…

My first project is to write a flash script that will emulate html image maps…

I have an 2D arcitectual image of a house and I want to be able to dynamicly load the image maps from a mysql table ( I got this figured out ) and have flash highlight the areas with a transparent polygon to indicate the defined area of the map as mouse moves over it…

So I need some info on how to create the boundries of the shapes, how to dynamicly draw the shape and fill it transparently, how to trigger say a popup describing the area under the popup, and how to assign the mouse press to act on that dynamic object…

Maybe some tutorial links would be great as well…

Thanks… Kevin
