Tire sizes

I have a rudimentary question about tire sizes. I have a stock 05 EGC with the nine spoke wheels and the stock Dunlops, and I'm replacing the tires for the first time at 13K+ miles. While I'm leaning toward a particular brand, my question is about sizing. There are several sizes, but I'm confused about the nomenclature of sizing. If I was wanting to swap to Metzler 880's or 888's what would be the correct size? MT 90 vs. MU 85? 72H vs 77? What gives? Can someone explain the sizing?

I've always been unhappy with the load/pressure data on a tyre sidewall and this website expands on the subject. Take the load and pressure info with a hefty pinch of salt! I have no qualms using higher pressures, especially on the rear tyre when fully loaded. The bike handles and rides better and more safely.
