Welcome to the planet and the best sport out there! If you're not scuba certified, you may want to consider it. I grew up in FWB and learned to dive there. The water gets deep quick and some of the best spearfishing is in deeper water. However the best thing you can do is start slow, get your experience level up and start doing more once you're comfortable. Good luck with it and hopefully you'll find a crew you can start diving with on a regular basis. Not sure if there are any clubs up there but your local dive shop in Destin is probably the best place to start.
