To get an accurate reading, you need to actually loosen the fastener
slightly first, and then retorque it.  The torque reading needs to be taken
while it's moving as the threads will stick together once they stop moving.

For common Loctite, yes.  It should not be used in places that require
periodic retensioning (like head nuts).  The retensioning is not because the
nut moves; but rather because the head gasket tends to become more
compressed over time.
