Full browser image with a semi transparent background

Hi All,

I’m kind of stuck on something and need to figure out what the best practice is to program it.

Currently I have link on an HTML page, and when the link is clicked, it opens a flash movie with slideshow and a semi transparent black background. The way I have it set up is as follows

CloseButton.as (the close button for the slideshow)
FullBackground.as (the black background)
MainContent.as (loads the slideshow)

then I have

main.fla (loads the CloseBtn, FullBG, and MainContent)
preloader.fla (loads the main.fla .swf)

That is pretty much my blue print. Is this a good approach for this task, or is there some other approach I should consider?
