For a traditional cup and spindle BB, absolutely chase the threads and face the shell on both sides. SOP

For a cartridge BB chase the threads only. You could face the drive side if using a BB with a shoulder on that side (like modern chorus bb), but it isn't strictly necessary. For a Phil Wood BB, neither side should be faced.
