Technically speaking, contravariant vectors are not vectors[/color].
Very good post. Just a minor correction. They are vectors, but not tangent vectors. (It's obvious from the rest of your post that you are aware of this. I'm just nitpicking a bit, because I think I would find that first sentence a bit confusing if I didn't know this stuff already).
