Swapping engines

[LoneWolfGal]

I've been studying a series of videos featuring Jake Raby, particularly one in which he demonstrates how to replace the IMS bearing and rear main seal. Raby is a fount of knowledge when it comes to Porsche engines, much of it esoteric. He mentioned in passing other parts that were candidates for replacement while the engine was out of the car:

oil pressure sending unit
oil pressure sensor (same as previous?)
fuel pressure regulator
rollers for belt
hose clamps
release bearing
air-oil separator (AOS)
crankshaft position sensor
positive crankcase ventilation conduits
grounding strap
VarioCam ramps
timing chain
cam chain guide ramps
slave cylinder on transmission
exhaust clamps

His recommendations were for the 99,000-mile demo engine in the video. Given that my new engine has only 39,000 miles on it, I wasn't planning to replace many parts beyond the IMS bearing and probably the rear main seal. However, replacing some of the parts in Raby's list makes sense to me. I would greatly appreciate additional advice about this, with my engine's relatively low miles in mind.
