The "suited ambassador" is called Kosh.
I think you are touching on some interesting things, and I think you will be very happy to know that all of your questions have answers.
I'm glad my questions have answers. As for Kosh, I should have remembered his name, or atleast googled it, but I'm sure it will stick with me eventually. It usually takes me a few episodes to remember a characters name, so I'll probably have his remembered soon
