Is it necessary to submit a Fafsa or only if I want need-based financial aid or loans?
Technically, there is no real deadline for the FAFSA. However, the school you will be attending may have a priority submission deadline as to when they want your FAFSA in order to review it and possibly to offer you need-based grant aid. Check the school's financial aid website to see if they have a priority deadline - they'll make it pretty clear.
A FAFSA is required to receive any federal aid, including Stafford/Direct loans, Perkins loans, and GradPLUS loans. Most likely you will need to submit it to be considered for need-based aid as well. So just do it.
