There is no such thing as "too many" clamps. I have a combination shop, both the heavy machines and a model building/electronics bench. I use many yards of the wire shelving made for closets to store "stuff" on.
And my clamps, and pliers, and anything else that will hang along the front, turned down, edge. Vise grips hang from a long piece of sheet metal fastened to the wall and kicked out at the bottom. "Carpenter" clamps hang from wife's metal shelves, we share them. I have dozens of "clothes pin" clamps that have a vertical board for them. Small at one end, large at the other.
What it comes down to is that each individual shop is just that, individual. Your clamps need to be located where they are handy for what you do. Advice is just like @$$holes, everybody has one and most of them smell pretty bad. Some of the ideas here are very good, but they won't work in my shop. I could go on and on about why, but it would chew up too much time and space. Many of my clamps can not be used for welding, they're plastic. Welding clamps that are useless for woodworking are out in the barn with the welder and torch. Everything pretty much where it's used the most. Give it some thought.
