Resize Flash File and make some changes

Hello, i need someone who can resize a Flash File to approx 1100 pixel width (at the moment it is 766px) without lost quality. I have the .fla File for Flash. Then i want change the soundplayer. At the moment it plays only one melody, but i want that the visitor can change the melody. Then i have create 6 html pages(some of them have iframe), these should be integrated in Flash. I have done this in html, because my flash experience was too low for that. So at finish, should all the site (together with the html pages) be in flash and should be fit in a 1280x1024 monitor size. I think if the flashfilm is 1100 width should be enough. I have upload the project so you can see what is to do: [login to view URL] For further questions please ask me. You should have some references, so i can decide easier. Thanks
