SCSI in Z-386/16?

I am the lucky (:-)) owner of a 16-MHz Z-386.  It has an ancient disk
controller which supports two floppy drives and two 40-Meg MFM drives.
Needless to say, I'm VERY short on disk space.  I'd like to put in 
a SCSI board--I was thinking of the Adaptek 1542 in particular--and
connect it to an external SCSI drive.  If you'll excuse my naivete,
I'd like to pose some questions for those with more experience:

1.  Is this even possible?  The Zenith BIOS only knows about the
MFM controller.  As I understand it, the SCSI controllers have their
own BIOS.  Is there a danger of the two conflicting somehow?

2.  Does the SCSI board need its own IRQ?  Is there a good one to
use?  (Besides the usual stuff, I just have an add-in board that gives
me two additional serial ports--I can reconfigure the board to switch
the IRQ's they use.)

3.  Are there some brands of SCSI disk that would be better for this
use than others?

4.  If I get the Adaptek board, could I also add an external CD-ROM
drive?  I know SCSI is SUPPOSED to allow you up to 7 devices, but I also
know it often doesn't work that way.  

I should add that my primary operating system is Linux, and my reason
for mentioning the Adaptek is that it's on the list of supported boards.
There are a few others, including the Ultrastore 14F (I think).
