Yes the drilled dropouts were a common feature of this frame builder, he often drilled the BB lug as well.
I'm actually unsure if the cups are Campag. They don't seem to be stamped as such.
I modified Swisstop yellows to fit the AX calipers to give better braking and protect the anodising on the rims a bit. The yellow pads are pretty soft. The original Shimano pads are very hard and abrasive.
