I can indeed see all of the files on that computer, including the boot
directory and everything under /

I don't know what to do from that point, though.

Here is the grub.conf from the working system, which is pretty much identical
to one of the non-working systems.  I assume that you mean I need to do
something to change and/or fix the root= portion of the kernel commandline, but
how do I find out what to change it to?

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-358.0.1.el6.i686)
        root (hd0,0)
        kernel /vmlinuz-2.6.32-358.0.1.el6.i686 ro
root=/dev/mapper/vg_ws195-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD quiet
