If you do remove the compressor altogether, then do two things: have a shop break the lines and capture the refirigerant, and keep the compressor for later. Maybe it's a holdover form the freon days, maybe not an issue anymore, but freon was one of the key "hole in the ozone" pollutants, so don't just vent it into the atmosphere. maybe not an issue, but play it safe. And keep the compressor, because someday you may want to sell the car, and I bet you are in a mnoirty of Floridians who never use AC, the next owner will probably want that thing.in

I don't think the free spinning AC pulley is going to cause that much power loss, and you never know when you might want it, maybe not for you but perhaps for a passenger. or some special circumstance. If you yank it, it will be expensive to put it back. However, if you want an easy half step, then follow the link in
