FAFSA. Am i going to ultimately have control over what grants and loans I take out?

basically. I am wondering about the process of deciding how much *I* borrow. How do I have a say in what is borrowed and at what step of the application process do I give *my* input on this? If yearly tuition comes out to 9000 + 1200 for books can I get a pell grant for 4310, stafford subsidized loan for 3500 and a perkins for the rest and THEN take out an unsubsidized loan for another 4000 and use it for personal expenses. *Or* does the school say, "he only needs 10200." if so am I not able to get the unsubsidized loan? Basically, I want money for transportation and a laptop but the school says they only approve 1500 for transportation and 1500 for personal expenses. Shouldn't it just be that I get the maximum? My efc is not 0 but it's pretty close.
