I would think that trying to use the flat rate tuition for TESU CS courses (10 credits in a term) would be a lot to take on, especially for someone who is working at the same time. I honestly could not imagine trying to do 18 or 20 credits in one term, even if they would allow it. I thought the max was 16 credits in a term, but when I went searching for that, I couldn't find it.
It's hard to guess what an MSCS program is going to consider enough graded credits. I was able to get into the GT OMSCS with my TESU BACS, and you can see where I got my credits in my sig. I had the advantage of TESU's old flat rate tuition which allowed me to spread the courses out over a year. I didn't do it that way to get the extra graded credit, but because the courses were not available as alternative credit back then. If I were doing it now, I would simply use all alternative credit instead of the mix of PLA and TESU courses that I did.
Grad school applications are a package. Experience can make up for academics to a certain degree. The main thing I've heard about OMSCS is that they are most concerned with whether they believe you will succeed in the program. They do not need to limit the number of students and are therefore not competitive that way. Traditional programs will be all over the map, and you would do best to contact the one(s) you would like to apply to and ask them the questions you're asking here.
If you decide you need the extra graded CS credit, I would recommend trying one term of the flat rate tuition, and be ready to either drop or extend courses if it proves to be too much to handle.
