At what point would Kerry have no longer been a commissioned officer? Am I right in presuming that he would have remained a commissioned officer until his discharge in 1978?
Would that status have any bearing on his meetings with the NVA and VC in Paris?

No. He was not subject to the UCMJ. If he violated the laws of the united states he would have been subject to prosecution in civil courts, just not military one's. His actions might have affected his fitness to retain his commission and his fitness to hold a security clearance, had those issues ever come up.
The point is that after release to inactive duty his assosciation with the U.S. military was a file sitting in a file cabinet of officers subject to recall if authorized by the Congress and so ordered by the President. But that is the beginning and end of it.
