Trash the bench and build one across the whole back wall and put a back and side on it so things won't fall behind it, make it as high as your beltbuckle, put peg board up there on the wall as well and string flourecent lights end to end. Put a power strip on the front of the work bench end to end. If it is two single doors you can also build a and 18" to 2' wide one in the front part between the doors, build this one on HD castors so you can roll it around. Is it a real 2 car 24x24 or 20x20 ?
Start scrounging any houses being torn down or remodeled look for wall cabinets that are being heaved, they make great storage for your oil, filters and any other parts supplies. When I did my parents garage I used cabinets one whole walll, the workbench was built with 4x4 for the legs and I built a platform out of white bricks across the back wall, 2ft deep and one brick high for the workbench to sit on, I could wash the floor then and not worry about getting the wooden legs wet.
