College Financial Aid Help?

Okay I applied ED to Syracuse University (the Newhouse school) and got in. Today I went to my profile on the site and it had updated financial aid info. I did fill out a CSS profile and submitted it, but have not yet done a FAFSA. My online profile says that I recieved a $15,100 dollar SU Grant, a $2700 work-study program (that I most likely will not take) and a $3500 Fed Stafford Loan. Are these numbers estimates or are they for sure? Will the money I get from FAFSA be additional to these awards or are these awards estimates of what the government will give me? Thanks in advanced for your help! :)
