Replying to Getting a job as a prosecutor

right now I'm in undergrad for poli sci and am pretty set on going to law school.  I had a question for NS before I go searching the ol' world wide web.  actually 2 questions:

1. I am planning on becoming a prosecutor before going on to become a criminal defense attorney.  my decision is based on the increased job security, experience, and connections being a prosecutor will give me.  anyone know someone who is a prosecutor?  what is it like being one?

2. does florida have some good law schools?
