Copper cutters, grit cloth, tape measure, torch, flux, solder (95-5 or 97-3) and drilling from the outside seems about right. Every situation is a bit different but what I do solder a piece of copper into the hose Bibb, plenty long. Make sure the valve is open when you solder so you don't melt the washer. Then once the hole is drilled I put the hose Bibb with a soldered piece of pipe through the hole. If you have to drill pilot holes for your screws mark those out and drill them, then reinsert the hose Bibb and measure mark cut clean flux and connect then go back outside, make sure the Hose Bibb is level and screw it in to your holes. Again make sure the hose Bibb is open an solder.
If you don't learn something new everyday at work, it's not even worth going.
