Some questions about using firefox to solve my purpose of autorun CD

I am required to create an autorun CD for my college conference to be distributed to the researchers who attended it. This CD when inserted in should first show an intro movie and after that 2-3 pages of description about the conference and then finally should put the control to an interface which can categorize, sort and search the papers available in PDF files.

Now out of many options i am considering to accomplish this, 1 way i thought of it was to fire up the portable firefox and create all the pages in HTML/javascipt and provide a nice interface for all of it.

1) Can i make portable firefox to open up with a default page whose location is relative to the current directory, thats going to be burned inside the cd and maybe copied to disk later. Can i ensure proper relative URLs
2) The version i downloaded have both flash and adobe pdf viewer intergrated with it. Is this going to remain the same even if the computer which is going to run the cd doesnt have any of it installed ???
3) Can i install addons into my portablefirefox and make sure they wont mess up somehow during operation from inside the cd
