The MSAR was the best tool I had for choosing med schools. It will give you information on the average stats of accepted students, the percentage of in-state and out-of-state students offered interviews, the overall curriculum style and mission statement of each schools. I would suggest focusing your search on schools that fit your experiences, not just your stats. Do you have a strong research background? If not, a 36 MCAT by itself is not enough to get you into top tier schools. If you have several years of research experience with possibly publications, posters, presentations, etc., you might consider a few top schools. Your sGPA is a bit low for top tier schools, and your MCAT will not entirely make up for that.
The best strategy is to narrow down your school list first by choosing your state schools, private schools, and other state schools that accept a high percentage of out-of-state applicants. Then eliminate any schools in locations you would not be willing to live. Eliminate schools that are way out of your stat range on both ends. From there, take a look at each school's mission statement and curriculum and choose the ones that seem to be a good fit for you.
I believe the average applicant applies to 15 schools. You have good stats, how are your ECs? Do you have plenty of clinical experience? If so, I think you'd be just fine with 15 schools. Are you limited by money? If someone else is paying for all of this and doesn't care how much you spend on applications, you might as well apply to 20 schools. If finances are very tight and your family cannot support you, consider applying for Financial Assistance Program (FAP) from AAMC and they will pay for the first 14 schools.
Hope this helps!
