I had this same issue. To be honest, I just chose my #1 program preference (OU-Tulsa's accelerated BSN) and started working on those pre-reqs. I'm taking my pre-recs at TCC, and OU's requirements are the same as TCC's + a few more courses, so I suppose if I don't get into OU, I can always try applying to TCC's program.
If RSU is what you want, and you like what you've taken there so far, and you meet will meet the average accepted
GPA/test scores/whatever other admissions requirements from past years they have (I'm not familiar with thier application process), then chances are when you get your pre-reqs done you will get in, I would think...you might want to meet with a nursing advisor and tell them your concerns - especially with the a&p, and ask them if they think you would have a good chance of getting in after completing them. They should be able to tell you if your GPA is competitive with past accepted students.
I'm personally glad I'm taking A&P seperate, because it seems like more schools in the area require them that way - and like you, I don't want to spend the time and money re-taking something I've already essentially taken, as well as some masters-level programs I'm looking at for way, way down the road.
Does RSU not require micro at all? Or is cell bio equivalent to micro?
