Go straight to a Motorcycle Safety Foundation (MSF) Basic Rider Course (BRC) immediately! Do NOT pass GO! What you need is in that course. I took the course in the Tampa, FL area and learned loads of good stuff from those two guys in spite of nearly 20 of riding experience. Get busy!
Also new member from Florida - Jacksonville. Agree with taking an MSF or similar course.
Last I checked Florida accepts the MFS (and other approved course) certificates as "proof of knowledge" and will waive tests. Walk into license office, show your certificate, and easily get your drivers license motorcycle endorsement. Then call your insurance company - most offer various some discounts for completing an approved course.
