Input Shaft Bearing Replacement
As far as how it relates to the CVT, not sure what the differences would be besides the fact that you aren't going to be taking the CVT apart if you have a replacement instead of trying to pull apart an MT to replace the synchros, ISB, or diff bearings.
Be sure the Honda tranny fluid you are using is for the CVT specificially, it actually will say continuosly variable transmission on the front of the bottle.

If you are under the hood, just be sure the key is in the off position and better yet removed from the ignition, there will be no high voltage electricity flowing to anything under the hood with the ignition off. Just the standard 12v stuff he is already used to. If it puts a shop owner at ease, have him use a T30 Torx driver and pull the small cover under the carpet in the back and flip the switch to off. Although pulling the 12v battery will also prevent the high voltage contactor from engaging the high voltage too so there will be no high voltage in that case either.
