Don, first of all congrats on the new camera. The deed is done so there is no more to say on that. Suffice to say its a fine camera, and as you are a committed Nikon man, its about as good as you can get. I would say that its spec will probably far exceed the needs of your photography
As for the Exif data, the Save for Web function strips out all the Exif info and optimises for the web. If you don't want tolose the data then you will have to use the regular Save As function.
For me, I always use Save for Web if posting an image on the net. I'm not too fussed about saving this data frankly. Other than a general interest in seeing what gear was used the camera settings are of little value so far as I can see. They always used to say that Rolls Royce's attitude to questions about engine and performance was that its Adequate. For me the same applies to the camera settings
