If you use the Radio Shack disk drive cable, jumper all drives for all drive
selects, as the select is in the cable.  If you make a straight 34 conductor 
cable, then jumper each drive for what it is, number 0, 1, 2, or 3.  The
select for the 4th drive is not standard, so you will have to 'jumper'
the card on the drive, not difficult, but not standard procedure.  The.
terminator should go in the LAST PHYSICAL drive on the cable.  If you are 
willing to only use 3 drives, you can have double sided drives, with LDOS,
NOT TRSDOS, with just a little mucking around.  Also, there are a LOT of 
'doubler' boards around, allowing double density operation.  

If your unit is uppercase only, lower case is easy to add with a character
ROM and an extra video RAM chip.  Even the old boat anchor Centronics printer
can easily be modified to lower case.  I had a friend who put auto power-on
and lower case in his for about $150 (then price) but if it cost more than
$50 today, I'd sell it for junk and get a new printer.
