It's hard to tell, but using the 8" wheels as a reference, I'd estimate your bumpers may be too high for the bumper zone... maybe the plywood is just the wrong height though?
Yes, the wood should only be directly backed by metal - if the sides of your robot are 27" and 37", the wood should be a 3/4" thick piece of plywood with dimensions of 5" tall and either 27" or 37" in length. It's also required to protect the corners, a good way of doing this is putting a 5" long piece of pool noodle inside the fabric of the bumpers at the corners. We normally put this vertical 5" long noodle on the ends of the 27" long segments, but it doesn't matter where they go. :-)
I'm certainly impressed with the time/energy and CAD going into this from a rookie team... I really wish we competed at the same regional - maybe championships! ;-)

Cool so we can mount our bumpers so that they go from 2" off the ground to 7" off the ground. if we have a 1" leeywat and the actual bumper is only 5" tall.
Also we will get the corner fixed so that there is no wood overlap.
We have few funds so we are trying to be as precise with our virtual work as possible before we start cutting and buying. need to minimze waste. If anyone has some fundage they could spare the kids in south Philly would be very appreciative.
