Importing flash project to actionscript mobile project in flash builder.

I have written my game slingshot game in flash and now I need to import it into flash builder and make the necessary changes to get everything on the stage in its proper place and make it work on a mobile device.  After that is done I will need an fxp file so that I can import the game into my own flash builder and continue working on it.  Please help.  I have included the zip folder with all my actionscript files.  I also already created the sprite sheet so the png file and xml document are both in there.  It just needs to be embedded and everything put onto the stage in its proper place.  You can see where I placed everything in the fla file.
