You will want a harmonic balancer--should have one anyway if you're going to
rev much. There's not a huge amount of magic to them, the older ones are
weights that are suspended in soft rubber (elastomeric) so they damp
vibration, other designs include asymmetric weights or balls that are damped
by a heavy fluid, and friction types that are just concentric rings. BFE
has some that seem to work just great and you don't have to worry about
getting the right taper and keyway.

Fot,
I do not use the mechanical fan so I want to cut off the snout of the
rotating fan hub extension. What should I anticipate if I just cut it off?
Do I need some other weighty thingy there? Who figures out vibration or
harmonic balancing acts? Is this another one of those black arts things?
