Excellent info - thank you all for the quick responses! I was hoping that I could simply hang the caliper out of the way to do this but was unsure. You gotta love these Bentley manuals - "To remove wheel hub, drop entire front end."

The existing valves do have the caps on 'em so thanks for offering that solution as well. I plan on using the heat/freeze method for removing/installing the bearing races - just waiting for the wife to be out of the house before I pop the hubs in the oven.
