Changing the regulator module is very easy. The brushes are attached to the regulator module so you get those for "free". The other items (bearing, diodes) you mentioned are much more involved to change. Per some of his comments I got the impression that the bearings are very good in the original OEM. The replacement bearings he has or can get might not be as good. I think the alt. is original and has 168k miles at this point and still spins very quiet. Still worse new bearings might be better than better 168k mile bearings.
Another thought I had....
The computer(s) in the car are very dependent on getting good clean power. It is a question - Should the computer be responsible for regulating the power?
