Hi Graciela,
You're fine, you can move to Florida as long as you let USCIS know about it. I'm going trough the same process (came with a J1 and got married with my boyfriend) and every time I get a notification from USCIS, they say "make sure to notify us if you change your address".
I filed everything 7 months ago, also did an expedited application for work and travel visa but nothing yet. How is it going for you? I don't care about receiving the GC soon, I just want to be able to temporary travel (I miss home!!) and work.
