However, since you brought up Schubert Calculus specifically, let me point you at this paper:arxiv.org/pdf/math/0608784v1.pdf by Ronga, which talks about a more classical perspective on the Schubert calculus. In fact, in this paper, you can see a picture similar to yours about configuration of lines. I think this purely expository paper gives a very beautiful picture of the incidence geometry.

Jan 26, 2012 at 5:15	comment	added	David Eppstein		My feeling is that this should be simpler in the projective plane than in the Euclidean plane — arrangements of lines in the Euclidean plane as you are trying to classify are basically arrangements of lines in the projective plane where you have one more line and you have fixed it at infinity, so the two theories aren't really different, but when you look at it projectively you don't have to make a distinction between triple intersections and parallel lines, they become the same thing.
