 If anyone knows the part numbers for the KDJ11 CABKIT or front/rear
 plastic panels for the BA23 that would help me contact suppliers. 
You know, Google is really simple to use...
A quick search on "pdp-11/93 cabkit" gave me CK-KDJ1E-KA.
Found, for instance, on

You can probably find information on all other stuff you are looking for
by using Google as well. However, finding the actual items might be
another story.
I wish you luck, though.
  My aim is to run RSTS/E v10 on this machine so I am
open to
 suggestions for the simplest path to this goal.
 I have a SBOX CQD223A/TM SCSI card which I would be willing to swap or
 sell for the QBUS variant or some other manageable RSTS/E compatible
 storage device. 
That is a Qbus controller, I assume you know this?
The Sbox is just a question of handles, which can be removed.
