yeah, the schools will want your parent's info 'cause they have their own F/A available (scholarships, grants) and want to give it to the students with the least support (which I guess they interpret to be the one's with the poorest parents). So, unless you want to be considered for these awards, you will not need to provide your parents' info to your school.
For the FAFSA, if you don't want to have to go quizzing your parents about their finances, just estimate their income and then choose the menu option 'Estimated Income from 1040A'...I've done this the last two years and they've never come back for actual figures. The info you provide will not affect your eligibility for the standard $38,500 disbursement, although it might preclude you (along with your previous salary) from scoring a Perkins Loan.
PM with any questions.
