Nifty idea for shelf supports, though a tad expensive. Strongly suggest you put a piece of wood at the rear of the workbench surface to keep small parts from rolling to the back and ultimately on the floor behind the bench. If shelf flex is an issue, you can add another support at the mid-point rear of each shelf. Also, have you given thought to a work-surface for static-sensitive components? How about AC power at the shelves? With test gear, you run out of outlets real fast.
The workbench surface... That polyurethane finish looks real nice, but I guarantee you it will get very beat-up in 5 years or so. Suggest you consider a surface that you can remove and replace every 5-10 years, like a conductive plastic or cheap flooring tile. If not, you need a very tough spray-on surface.
Nice work bench, but you have gone over kill with the size of the materials that you have used. To make the work bench to easier to change I would have butted the work surface up to a back board. A easier way you could have built this bench, would have been to use 2"x2"x1/6th angline, (that's a long 'L' shaped piece of steel with hole and grooves cut into it). That would have made a great framing for you to mount worktop, shelves and back boards, as well as making it easy to replace anything that needed replacing.

I like your thinking!
