Career changer, need advice

Hi, I have been reading through the forums and it seems that I have found some similar topics to mine, but not exactly.

My background is in healthcare, I was a RN for a 3 years, then I transitioned into a health insurance role, where I audit medical records / claims (2 years experience)

My goal is to become a financial analyst. I have a 3.2 undergrad GPA. Currently studying for GMAT.

My questions are: (please try to answer all, thanks!)

1) What steps do YOU think I should take to start a career in finance?

2) Should I apply to grad school NOW or wait? MBA? Would MS Finance be a better option NOW???

3) Should I jump into an entry-level accounting role for a couple years before getting an MBA? HOW would I even get a job like that without a background?
