Strange.  I have a NEC CD-ROM drive on my machine and I am pretty
certain the switch settings are per the drive manual.  In general,
If this is the last drive on the chain, termination should be on.
SCSI2 should be OK.  You should be able to see the drive with
diskinfo if you have the SCSI ID and driver major/minor set correctly.

Yes.  However, this is only for sam.  You should be able to manually
mount/umount the drive.  The busy error indicates that some process is
trying to open device file (possibly, because you have the device listed
in /etc/checklist).
