Sound like you are mostly interested in south Florida. I'm in the Florida Panhandle, a long way from the Miami area.
I have read a good bit about fishing Peacock Bass in the canals down there and it sure looks like a great deal of fun. The most famous lake in Floirda is Lake Okeeochbee in south central Florida. Just search fishing Lake Okeeochbee and you will get hundreds of hits. Many will lead to peacock bass information.
If you are interested in crappie fishing go to www.crappie.com
and to the Florida thread. There is a very large and active snowbird community that winters in central and south Florida and they really know their stuff on crappie down there.
Hope this helps a little.
