I don't know about dual (Com1/Com2) style cards but I've used a standard
AT class card with one port on it with reasonable success.. You can also
use your typical PC style parallel card as well or even so far as a 
monochrome adaptor with parallel port... The bus is compatible... If
you have an EGA monitor/card that you wanna use, that should work well
also.

I'm assuming the 6151 is the same as the 6150 except with less slots and
a different case/power suppliy.  I've worked on them and haven't found
any other incompatibilities... The drives are set up in the same manner
as you would set up PC drives except that the VRM only supports 3 physical
disks as opposed to the 4 that you could fit on two controllers... (without
going to scsi)... You can even mix and match controllers.  I have an RT
with 2MFM drives and one ESDI drive... The setup seems to work reasonably
well.  If you're unsure of how to hookup PC drives, then just ask any of
the PC people.  I'm late for work and don't have time to describe it.  It's
fairly simple.

I don't know what this one is.  I also have one and borrow a 6157-002 
drive every once in a while to backup my system but that's as far as
it goes.  I'd like to hear someone say that it's SCSI so I can steal
a drive off one of the Apollo's at work, but I'm pretty sure someone is
going to disappoint me..
