I'm not sure why Sailorette posted that information regarding ADS programs, as I can assure you that a great deal of those programs do not focus on teaching, but rather research (e.g. Illinois, Ohio State, Cornell, Arizona, USC, etc). Actually, nearly all of those programs are research focused, as you will find that a lot of PhD programs are. In fact, I'm quite sure that if you are honest and even mention your keen interest in teaching you will be automatically denied admission to many of those programs. They are not interested in producing teachers, but researchers. Of course as a professor, one of your responsibilities will always be to teach, but that is not the focus at all. In general, any of the "top" accounting programs, like say in the top 50, are generally going to be research focused. In fact, the PhD is really a research degree. If you're interested in primarily teaching as it sounds like you are, a masters degree is the better choice. However, as greg mentioned, generally the less competitive programs may have more of a teaching focus (although ultimately all PhD programs' main focus is research).
Since you specifically mention Ohio State and Duke, I'm sure you are aware that they are both one of the top ranked accounting PhD programs. Admissions to either is honestly slim. You have a great undergraduate GPA as well as GMAT score. However, that will probably not be enough to set you apart from the other applicants to those programs who will probably have similar GPAs, GMAT scores, MS accounting, work experience, etc. I am in no way trying to discourage you, but you have to realize that getting into either of those programs is extremely competitive, especially given the fact that they only admit 2-3 students a year out of perhaps a hundred or more applications. What this means is that your profile can not just be "acceptable" but must be outstanding.
As for your original question about getting into a "good" PhD program, it really depends on how you define good. Generally a good PhD program is one where there are several professors that share your research interests. If you are able to communicate why you are interested in a PhD and align your research interests with those of professors at your chosen programs, I'm sure that you stand a fair chance at getting into at least one "good" program in the top 50.
