"All we really "know" is that the redshifting of that very old light, WAS apparently non-linear with distance at the time it was emitted"

The redshifting has always been non-linear with distance. It's only approximately linear if you look out to small distances (Hubble's Law). It's the same reason the Earth appears flat on human scales.

"If that is not so now in the comparative observation of closer sources, then the Expansion is slowing down!!"

Actually, current observations show that it's speeding up. If the distance increases more quickly with redshift than Hubble's linear relation, you have acceleration. If the distance increases less quickly than Hubble's relation, you have deceleration. The first case is what is observed.

"Does this not follow what we would expect from the transition of Inflation to Expansion?"

The Inflationary Epoch is theorized to be at much earlier times than we are observing. Thus, the universe must have slowed down after inflation and then sped up again later (around our time). Who knows, maybe it has been oscillating back and forth.
