un/Subsudized Loans. What steps should I take?

I am in a postbacclurate teaching program that is split into 3 semesters. Tuition is 4.3K/3.3K/3.3K.

My aid for this semester is:

Subsudized: 2750

Unsub: 3500

Teacher Waiver Fee (?): 455.

Anyways, the total offered is 6705. Do I take it all?? How does that work if my tuition is 4.3k for example?

What will my payments be like after i graduate? Lol thank you for any advice.
