How do I move a video project from Encore to AIR via Flash Builder?

I've got a rather complex video project with lots of submenus (that works as a DVD - so it is "debugged") that I need to be able to export from Encore into an app to upload on the iTunes store and Android Market. So far, I've managed to export the project via Encore's Flash output and test the results using a web browser (it works). Everything got saved in a new folder structure with an index.html file pointing to the flashdvd.swf file pointing to the AuthoredContent.xml file that actually holds all the information on the file structure (there are 99 files in the Sources subfolder) and uses the default generated Theme.xml file.

What I need to do is to somehow import all this into Flash Builder as a project so it can become the source for the various "app" platforms. My questions are:

1. I've got Flash Builder 4.5 - do I need to upgrade to 4.7 in order to import the project or can this be done in 4.5?

2. Is there some intermediate step that I'm missing?

3. Will Flash Builder be able to repackage all these files into the file specs required by each target platform (I'm assuming it will - is that a valid assumption)?

And moving downstream a bit...

4. Since this is a video based project with over 200 megabytes of F4V content, how will the content arrive on the end user device? Will it have to be  streamed or can it be downloaded? - this is a big issue should the app become popular and we be forced to maintain a streaming server somewhere. What about server sizing in such an event? For example: is there a way to estimate how much bandwidth is required per 1,000 instances?
