I agree that all of those are great questions. but many of them can be found out BEFORE you go to an OV. It's called doing one's homework beforehand.
This can be done simply by having your son discuss some of these during phone calls or email during the recruiting process. The early answers to the questions would, I presume, lead to interest or none interest in a program before one gets to the end process which is the OV.
Very easy to find out many of these answers by visitng a team or the college's website. There you can find a wealth of information. There are even some sites that have places that you can submit questions regarding academics. There are many questions regarding admissions and academics that coaches cannot answer and won't in case of wrong information.
Use common sense.
However, there still are a few questions in your first list I wouldn't go.
