Heather - welcome. I'm a PA & MD transplant. I've been down here for 2 1/2 years. One of the 1st things I was told was "forget everything you knew about gardening up north". You really don't need to forget everything, but FL gardening is a learning experience. The basics of having good soil never changes.
FL native plants are always a good place to start. Once established they require less "care" than plants you are forcing to be happy. Mine thrive in the un-amended sandy soil & only get watered when it rains (which has been very seldom over here this year).
I know there is a County Extension Office over there. I'd definitely get in contact with their Master Gardeners & get some area specific info from them. And look for the good nurseries & talk to the folks that work there. Some Ace hardware stores also have really nice garden centers and sell local plants.
Good luck & happy gardening.....................
