Reconstructing a flash file

I have a flash file thats been on my comp. that I’d like to modify, I’m pretty new to flash so I don’t understand to much of AC etc. Now the file and its resources are broken/seperated…there’s a timeline as, an action as. pictures fla’s, text fla’s etc. It’s an animation.

Imagine the flash as a banner. Now what I’s like to do is change the design/pictures of the banner not the function, how it works. So the resources are as mentioned are seperated and my question is…how do I “merge” or reconstruct them, how do I get the into one event so to speak? Thanks for any help.
