I was in your shoes a few years ago (researching ADN programs in LA & Orange County) and found that just about every school has slightly different requirements and different methods for selecting students.
Every school will require you to complete general education courses in English, Communication, Math, History, Humanities, and P.E., so those are the courses you will want to do first. Although it depends on the program you apply to, most will want your science courses to be taken within five years of applying to the nursing program, so those are the ones to save for last (so they don't "expire.") Every ADN program I looked into requires Anatomy, Physiology, and Microbiology. On top of that, some of the community colleges also require you to take pre-reqs (such as Chemistry) before taking Physiology or Micro -- try to find a school that doesn't to lighten the load a bit! :)
When I first started doing my science pre-req's (5 years ago) I went to Cypress, but found that it was really hard to get into courses because they were all full and only took a few petitioners! Golden West, on the other hand, had a lot more course openings to begin with, admitted more petitioners and had instructors who would give priority to repeat petitioners who were turned away the semester prior. I ended up doing all of my science classes there.
Some ADN programs use a GPA point system to admit students, some schools use a lottery system, some schools use waitlists and some don't.
A few other schools you might want to look into that I did not see in your list are Harbor, El Camino, Glendale, LA County, Long Beach City, and Golden West.
Most of the schools post their pre-req's and information on the application process online. The BRN has links to the websites for approved programs here: Board of Registered Nursing - RN Programs
