Thank you for your guidance!
Did I read correctly on that link's page that instructions will be included with the order? I can take apart my Roomba enough to expose the brain board (as was necessary for the replacement of the sensor array and the cylindrical IR sensor) and I am technically inclined enough to solder, but I do not recognize this sensor board immediately and don't know off of the top of my head where they will go. I have become accustomed to tinkering until I've figured it out, but instructions are always a welcome addition to the process!
I can solder all day long, but I make no claim to be anything but a hobby roboticist.
