For a start get a USB zip drive or even a multi card/zip unit, make the bootable HD with the o/s as primary master, the main optical that you will use as primary slave, the other hard drive and optical IMO as whatever you will use the most and make that secondary master. My experience is to keep the optical readers/writers apart, especially if ya want to burn, if you need to use two of those four predominately and together place each of them on a different channels that way no transmittance interferences down the same ribbon will occur, this does not happen with SCSI.
But this is my version of what I would do and I am sure there are other opinions in this regard. Good luck. :smile:
