Hi Buddy
All you need to transfer the style files from Bill's web site is a floppy disk.
Download them to your hard disk on your computer and then transfer them to your KN7000 by means of a floppy disk...probably about 10 at a time.
They will appear on your KN7000 in the rhythm area button marked 'memory load' and you will then need to save them to an SD Card to retain them.
Incidentally there are laods more downloadable style files on the internet.
The rest of the kit you mention is for audio files such CD's etc
