Usually not a good idea, IMO. The camera is going use the AF point on the closest subject (or part of subject, or foreground element). Usually, that's not what you want. I prefer to choose for myself what the actual subject is (generally for portraits, that's the eyes).

Yes, calibration should always be performed with the center AF point. This is especially true for f/2.8 and faster lenses, since the center AF point is a high-precision point with f/2.8 and faster lenses.
On a 5DII at 200mm f/2.8, the DoF should be ~3.5". Instead of a flat sheet of text, have you tried shooting a ruler or focus target at a 45° angle? You can use a chart like [url="http://focustestchart.com/focus21.pdf]this linked one[/url], taped to a door so it's easy to get the angle.
