MFA programs don't care about your CV or your extracurricular activities unless your applying for a TA-ship and then they only care about teaching experience. They don't care if you've been published or what school you went to or your grades unless your grades are so low you obviously wouldn't survive in grad school. Your writing will make or break your application and if you and another applicant happen to be equally desirable they will look at your personal statement and letters of rec. I'd focus on finding recommenders who are excited about you as a student and human being and will have something unique to say because the schools don't care how famous your recommender is and choosing a well known person over someone who knows you and will put a lot of heart into the letter they write for you will ultimately hurt your application.
If you are choosing those schools simply because they appear to be the Ivy Leagues of MFA programs you might want to expand your list. There are several dozen schools that have amazing programs. Ask yourself if you want a two year or three year program. Do you want a TA-ship. Do you want the opportunity to work on a literary mag. You said you've published poetry and Creative nonfiction so would you prefer a program that encourages cross genre exploration and even lets you produce a mixed-genre thesis. Which cities or states would you be happy living in. Does the program have visiting writers or writers in residence. Do they have a student run reading series. What sort of career guidance do they have. Do they bring in publishers and agents. Are they truly fully funded. Iowa doesn't guarantee funding for the last year and some programs claim to be fully funded but the TA-ship or fellowship isn't enough for the city. Some don't waive tuition but rather make you eligible for in state tuition.
So many people get sucked into the glamorous Iowa/Cornell vortex, but many people who went to those schools don't publish, don't get teaching jobs, don't produce anything remarkable and plenty of people from other programs write woundingly gorgeous books. You only get an MFA once so choose the program that suits you not the fanciest program.
