Contrary to the multiple replies of "In a downpour, there's nothing that will keep you truly dry" or "Even with the best rain jacket and pants, you will be soaked from sweat 15 minutes after you put on the rain suit" you can wear a breathable 100% waterproof jacket and not sweat to death.
I ride for hours, in complete downpours, and end up no more wet than wearing my softshell in non rain conditions. But the warmer temperatures of florida may make the sweating part too much. Almost all of my rain riding is in cooler temps. Summer here is 70-80 degrees, I just get wet but thats warm for us. For you thats probably cold :/
Legs I dont even bother with waterproof. Hot= let them get wet, cool I wear leg warmers and let them get wet but stay warm, cold = I wear windproof tights and let them get wet but stay warm.
Jacket I use a showerspass. Everyone who says you sweat too much are people who got burned with goretex and havnt tried new event material. I'll let you do your own research on it.
