Mariner9,
As you mention my list was not order specific. I think your order is a little better.
Also to be added to the list is "courtesy" as in don't cut in front of aircraft because you think you have time or are faster.
As for to much reliance on the radio....I am not to sure on that one. In the states it is not so bad becaue there is so much open airspace. In the UK especially the Isle of Man there is not much space to fly about in. And there is far to many bell ends out there not using their eyes and brains.
