Both those things are easy to find online for yourself.

If you download the program PsxMC (just google it, you'll find it) you can use it to rip all the FMVs from any PSX disc (including FF8, and any other FF on a PSX disc). The program automatically saves them to your computer as .AVI files, easy to use. You can play them on Windows Media Player and edit them and whatnot. I use it to make all my music videos. The program also saves image files and stuff.

As for the script, the complete FF8 script is at http://rpgamer.com Just look under FF8, you'll find 'em.
