Career change

I used to be a EMT-B, let it laps about 2 years ago. I was volunteering doing that while I worked my way into my current career, airline pilot. Now I'd like to get back into the healthcare field. My thoughts were mainly of getting my RN, some friends have mentioned PA as another option but the prereqs for that are a little out of my grasp at the moment, so a RN is my first choice. So my question is wether or not getting my RN will meet some of those requirements?(Human Anatomy, organic chem, ect...) and whats the best way of going about getting the RN since I'm in a non medical career field? Idealy I'd like to get hired at a hospital and then have them pay for my schooling. How likely is it that they would do that? Also anyone know of any type of nursing scholarships or programs with work agreement for individuals pursing health careers as Registered Nurses? Preferably someplace in NH or MA.

Thanks for the help.
