Did you buy your condo through a Realtor? If so, they can provide you with the information you need.
If not, just google the DMV (division of motor vehicles) and ask them how to proceed with regards to your license and also a tag.
As far as insurance for your car, do the same. The 2 best places I can recommend would be progressive and Geico. Progressive will give you quotes from several other companies, but make sure you are comparing apples to apples.
It wouldn't be a bad idea to google the local chamber where you moved to and get one of their welcome kits for newcomers to the area. It is usually chock full of info that would be helpful regardless of whether you are from another city, country or State.
Congrats on the move and welcome to the sunshine state!
