Based on your current options, I think you have some good prospects for merit scholarships! Most of the schools I have interviewed at don't look at financials/FAFSA/etc. for merit scholarships. It might vary by school, though.
Some schools I've seen say they need the FAFSA for any aid at all. Other schools started giving merit aid alongside acceptances back in April, pre-FAFSA, so presumably they don't require it. 🙂
