1. I retook my MCAT in June the year I applied but if I remember correctly, KCU gave me their secondary before getting my results back. It was however discussed in my interview (taking the MCAT again) so it's not any less important than your first test.
2. I think you have to take everyone's match list with a grain of salt. I'm from Florida and as of now, I'm looking to come back and do my residency somewhere here. While there are a few matches from KCU in Florida, it's definitely not a lot, but I think that has to do more with interest in the state than not being able to match here. I imagine the same would hold true for California - you may have a better chance of matching in CA if you attend a school there (just because majority of students at any school seem to stay within the state or neighboring states), but I don't think attending KCU will hinder you from it, especially if you do well
