I thought they asked some of the most crucial information for potential Ph.Ds especially the questions in the "Faculty Reputation and Activity Measures" section and the "Funding Measures" section. From what I understand there are ways to find out what happened to the alumni of the program on some graduate school website.I know Cornell have a list of places where the graduate students went off to after they graduated. But, I agree. I think it would be much more useful if they included the questions you listed.
This site would definately be helpful when I apply to graduate school.
