Probably depending on the local CAA and company; personally I've done it on initial and then at least once every three years.

Nope. As it was mentioned already a few times here: after disabling electrical trim, manual trim handle(s) can be pulled out of trim wheel and stab handcranked into desired position. Not overly difficult, at least in sim.
