Help on zoom navigation and auto scale stage

hi guys, can anybody help me with my project?.. I’m trying to make a navigation system with the source I found on fffiles. it’s supposed to apply zooming in and out and also panning right and left to items that created on the fly using some array.
and I also want to make the stage and the object itself to auto scale based on the resolution of the viewer’s browser.
so far all I can achieve is all the above minus the auto scale on the menu object, I can’t seems to get it to auto scale or auto placed when I resize the stage. and also how can I add blur filter so that the further an item from the viewer it gets more blur…I’m not asking to much am I?..hehe…
can I anybody help me, please
I’ve attached the fla for your convenience
thanx
