That being said I think this list of questions is excellent. I would be much more inclined to hire someone who asked these questions than someone that didn't.
Somewhat conversely as an interviewee I would be at least slightly concerned with a company if I had to ask these questions. This is basic ground that any good interviewer should cover in an interview and if thy don't they may not be looking for the type of development styles that I like most.
Interviewing is a two way thing both sides should be choosey and neither side should settle for something less than ideal. If we all found jobs / employee that we love then the workplace would be some much better off for it
