Hi Josh,
I love the three questions that you have posted on here. Unfortunately, I am not an expert in these areas. However, I am sure that if I can't find the answer soon that someone else will.
Just from my gut instinct (and by no means a well researched answer), I think you have to evaluate how many courses you have left in your standard, private university. I cannot speak for the online universities at this point, but I know many standard colleges do not accept more than a few courses from another college. I have a feeling that each college will have a slightly different outlook on the issue so that is something you would want to ask the online college. You may end up having to do the math. Which is cheaper? Taking the rest of the courses at a standard university or possibly taking a longer time with your degree and taking more classes at a potentially cheaper online university.
I hope to have more information for you at a later time, but I hope that information helps you at least with your thought process for now.
