I don't think that you should take off schools from your list just because you lack research experience. Adcoms may see something else in your application that is different from what the typical pre med does (i.e. youre a charge nurse at Stanford) and that may give you an advantage. But, if you insist on removing schools based on how "research oriented" they are, I would recommend looking through the MSAR. See what percentage of students entered each school with prior research experience. Additionally, if research is required during medical school (i.e. Case) then it is more likely that you should have some research experience prior to medical school, although not absolute. On a side note, I was looking through the book and found two interesting facts: at Vanderbilt (96% of entering students had research experience) and the University of Utah (97% of entering students had research experience). They werent on your list, but I thought that they were cool statistics. In concluding, you will see that most of the top tiered schools have high 80s to low 90s of % of students entering with research experience. Most schools have mid 70s to low 80s in terms of the percentage of students that enter with prior research experience. Though these numbers are relatively high, there are students that do get in without research experience. If possible, however, I would recommend testing what research is like, whether in a lab or doing clinical research (you have a year). At least this way, you could learn whether you like research or not. Hope this helps!
