From florida you will pay about 1200 to ship the vehicle and then pay the taxes on the inflated value of the vehicle that Hacienda places on the vehicle when you go pick it up. I sugest you search this site about shipping a vehicle / car, most of the procedure is documented and also the site where you can enter your VIN number to determine what the taxes would be.
By law you are required to get a local driving license within 90 days of moving to the island
The eye test is mandatory, no way around it.
As to address .... your house will not be build overnight, so you will be living some place in the mean time, and unless it is an Airbnb or a hotel, you will need to turn on utilities so you will have a bill.
I am not sure if the sales deed will do or not but I do not see why not. But you will be living someplace in the meantime so either way not a problem.
Calling Hacienda is a waste of time, they hardly ever answer the phone.
You will need to get insurance, the Marbete (inspection sticker), new registration and plate, and register your car within 30 days if I remember correctly. There is a mandatory 135 dollars a year liability insurance that is charged to you when registering the vehicle if you do not have other insurance. It cover up to 4k of damages to others, the rest is yours.
