"As Einstein thought, C is the limit, so I would have to assume, since he was right about a LOT of things, that Gravity would travel at C as well."

Perhaps, but Einstein has also been misquoted on quite a few things, too. That's something to consider.

Another thing to consider is that Newton was a rather clever fellow, too, perhaps even in Einstein's league.

...And Newton says that Gravity propagates at near instantaneous speeds.

That's something else to consider.

And Newton says that Gravity propagates at near instantaneous speeds.

Lets try a different tack.

If you have a flat sheet of rubber and you place a large ball on it, you will see a curve. If you roll a smaller ball near it the smaller ball will curve due to the bend in the sheet. This is a good analogy of a gravity field. This sheet is there all the time. However, a wave can be created in that sheet which will then propagate (but the original curve will still be there) along the sheet. If this is a gravitational field and a gravity wave, that wave will propagate at the speed of light according to General Relativity.

I am not sure I am saying this very well.
