Flash Scripting/Multimedia

I have created several short animations to be published on a website. I have not been able to successfully view these files online because I do not have a full understanding of preloaders and flash players. My server is ready for flash, but I lack the knowledge to make it all happen correctly. What I need, is for someone to create a script that will provide streaming/progressive downloading of my flash files so that they play immediately with the push of a button. (and of course finish downloading in the background) This action script needs to be in a "template" setting so that the only thing I have to modify on the action script, is the title of the .swf file that is to be played. If successful knowledge of preloaders is proficient and needed...additional assistance with that will be required as well.
