Do you have other lenses to check it out with? It could be either the lens or the body, and knowing which lets you just send in the faulty item instead of both the lens and the body.

Actually, the focusing screen is for you, not the AF system, so no, it couldn't cause the problem.

You might want to take a look at your lens specifications to see what the minimum focus distance is. It appears from the picture that the bottom of the picture is blurred, while the top is in focus. If, as it seems, the bottom is the part nearest you, it may be that the subject is just too close.
As TCav says, try out the test chart under controlled conditions to see if you really do have a problem.
