Ok, before you decide anything, go talk to your college. They are the best source of information and can answer whatever questions you have.
If you do qualify for financial aid (which you probably will, its just a question of whether its grants or loans), it will cover your tuition and possibly books. Most campuses do a book voucher program which will allow you to purchase or rent your books from the onsite bookstore by debiting it out of your financial aid balance. Note: It is cheaper to buy them online usually, but this will cost you out of pocket. Renting is great, but its usually a wash vs just reselling your books back after the end of term, which you can't always do (so it's a bit of a gamble).
I know looking at FAFSA it might say you are eligible for a 5500 grant, but you're probably looking at only about 33% of that back after college expenses. (Again, talk with your school)
If you need help with childcare, housing expenses and food; one possibility is to inquire with your local DHHS program (IE Assistance Programs). I know some people view this negatively, and if you're against it, then by all means don't. But they offer help for situations like this that you might find beneficial.
Loans are a benefit, but they can quickly become a noose if you have difficulty paying them off. Again, talk with your school.
If you can manage it, I would recommend attempting to work part time while going to school and avoiding the loans. This way, even if you decide school isn't for you, or if something happens after you get your degree that impairs your earning ability, you do not have to worry about the added burden of paying off the loans.
