'external' MC control

Hi everyone…
I’m making a website banner which has 5 MC’s. Each MC is a simple tween, consisting of a single picture starting in the ‘background’ where the alpha channel is increased until alpha=100% and the picture is enlarged, brought to the ‘foreground’ then 2 seconds later, the process reverses and the picture disappears to the ‘background’ again.
Running at 32 fps for smoothness, each fade in/stay/fade out takes 218 frames.
Each picture is in its own MC, and they have been made so the first x frames until its turn to tween are static, as are all frames after the tween.
It has all been done through manual tweens, no AS is involved.
What I’m wanting to do, is when a user clicks on any of the 5 pictures, whichever picture is being tweened goes back to its ‘background’ state, the picture that was clicked comes to the ‘foreground’, a small description of the picture appears, and everything freezes in place until any place on the .swf is clicked again, at which point the picture that was clicked takes its normal 2 second tween to the ‘background’, and the scene continues from where it was.

The other thing I’d like to include, as a part of the tween, is that any picture in the background has a 2 or 3 px gaussian blur applied, and anything in the foreground is sharp, is this easily doable?

Here’s what I’ve got at the moment, as a .zip’ed .swf so I can upload it
