She insists on using a torque wrench.
Is this really necessary? and if so what should it be calibrated at.
I have never used a torque wrench to change cassettes
Depends on what you mean by "lockring tool" and "tighten by hand".
If you mean just turning one of these with your bare hand, then no, that's not gonna be good enough unless she has incredible gripping and arm strength.
If you mean something like this, then yeah, tighten by hand should be fine, don't be afraid of the clicks.
Same with the mother of all cassette lockring tools:
First style tool with a 12" crescent or a socket wrench with a standard ratchet handle will fork fine, too.
