I would only quibble with #4. Shooting wide open, or nearly so, allows you to isolate the subject from the background, which is one of the reasons pros buy fast lenses. At a recent seminar by our local paper, which employs 9 pro photographers, one of the key points made by almost every presenter (portraits, photojournalism, sports, weddings...) was to shoot wide open or a stop down to isolate the subject.
If there had been a landscape photographer in attendance you would have heard a different point of view. In another post rehess recounted taking pictures of his daughters in a school play, in that situation using a wide aperture to isolate the girls would have resulted in images of them without context. I would venture to say if one of your local news photographers had been assigned to cover the play and did that, the editor would have had a fit. Isolation is the current "in fashion" trend, but there are many times when it is just wrong. A picture of an eagle against a clear blue sky is boring, include it's environment and the image tells a story.
