I need to know which economy lot to use for southwest? And what is a good time to get to airport for 6:35am departure on Thursday also for southwest?

We actually got thru the airport and security pretty fast. But you should give yourself 2 hours for sure. Can't help you with the lot sorry

North Park Place is the most convenient economy lot for Southwest. We recommend arriving 2-3 hours prior to departure but this also depends on whether you have membership with Clear or TSA PreCheck, or if not, have you booked a time to go through security with the free MCO Reserve service?
