"And the later impact (1150 BC) was the more familiar Yucatan strike?"

The Yuchatan Strike was named Chixlub(sp) and was 65 millions years ago. The dino killer, it was.

"And is there a discernible fit with the underwater city off the western tip of Cuba?"

Glad you asked. I found this while looking for support for my theory about the underwater Cuban city. It occurred to me that 2200 feet is a lot of subsidence, so I have proposed that the Gulf Of Mexico was blocked off (like the Black Sea) during the last Ice Age and dried up to some stable level and these people actually built this city/structures on the coast of the lowered Gulf of Mexico.
I was looking at some underwater data and saw some curious round depressions just south of the Bahamas and went looking for impacts that may have broken the 'dam' to the Gulf of Mexico. I came across this article in my search, which lends some support to impacts in the region.

For which I earn a great, big "Duh!"

Thanks very much for all the info. The global relief map is incredible. But I'm still waiting for it to download (28.8 ISP)...
