Trish the airport is quite small and doesn't take long to get through. The Delta agent I asked about this last week said about an hour is good to get through. TSA told me be there two hours prior and Delta originally told me at least 3 hours prior but the airport only opens 90 mins prior (usually around 6A +/-) to the first flight.
The Airport opens 90 minutes prior to the first flight, and closes 1 hour after the last flight. Flight times vary daily.
