Hi there! I'm a pre-nursing student at Sac State also, hoping to get in for Fall 2016. I can answer some of your questions. Nearby nursing programs from the schools you mentioned have similar prerequisites (Some have more prereqs, some have less. I suggest looking into each of their prereqs) but different application requirements than Sac State. About the repeat policy. You will not get deducted if you take a different class than the one you have already taken twice. So for example, if you took Sociology twice and were not able to get an A, you could take another course that is applicable to that corequisite area. So yes, you can take a different class and will not get deducted points (:
