Ultra Torque Bearing Service/Replacement?

I'm about to install a Centaur Ultra Torque crank, and I'm wondering how I'll replace the bearings when the time comes.

My LBS probably won't be much help. Will I need to go to a machine shop for this? Has anyone done it at home? I'm assuming the bearings are on the shaft pretty tight, and some sort of special extractor is needed for removal, with a press needed for installation. Is that right?
