What Program Should I do? Should I consider a different school? Any Suggestions

Hello everyone! So, my situation is very rough at the moment, so here is some background before my question really. I recently graduated with a GPA around 2.36. (There was a lot going on that really affected my performance but to say that it was only that and not my own doing also is a lie) .I was able to get into a couple different master programs on conditional admissions (one being for a Master of Public Health in Epidemiology and the other for a Master of Science in Microbiology-Immunology). I understand that with my undergraduate GPA getting into really any program(s) is going to be hard (if not borderline impossible), I looked into DIY, but because of my uGPA that is going to be a very long while (3+ years), so I need to somewhat reinvent my GPA.

I am planning to take a couple courses throughout the summer that are offered at my CC that should help raise my initial GPA, and 3 of the 4 are considered for the sGPA.

I was looking into SMP programs, but there are so many, and I know some would and/or have not accepted me. Is the Harvard Master of Liberal Arts in Biology degree something that would be an option?

THE QUESTIONS
Essentially, I want to know,

1. should I continue taking one or two courses while also pursuing a master's degree?

2. Should I pursue one of the two master programs I have been accepted in already?

3. Are there other programs that I should consider before I commit to one of the two?

4. Any additional tips or anything?

(Thank you in advance and sorry for the lengthy post)
