I would put the 80GB IDE drive as Master on one of the IDE controllers and move the CR-DVD and CD-RW to the same channel as Master/Slave.
As for your Ghosting, I've used Ghost to image two 20GB's (RAID0) to one 40GB drive in pretty much the same setup you're describing. It was FAT32, but I don't think w/ the newer version of Ghost you will have problems w/ NTFS. I was using 7.5 Enterprise.
As for the program, I wouldn't settle for anything less than the real deal,
