With regard to the back panel of the bench, I would suggest that you frame around the inside with 2x2 pine or something of that nature. Make sure it's flush with the edges. That will give you something solid to screw the back panel too and provides some additional support.
I would also go down at least one side of the divider board on at least one side with 2x2 as well. The felt weather stip material common in most hardware stores makes a good seal. Don't silicone the rear panel.
If you add the Superflow type top section with a steel or aluminum top plate, use the felt material or rubber to seal that as well.
With the top and back removable, it makes everything so much easier to access later for maintenence or changes.
