I'd think that for any of the sleds you have listed, an airdam would be your most cost effective solution. If you keep the air flow under the car at a minimum with an effective airdam, belly pan mods would be unnecessary.
If you lower your ride height, I'd guess you would reduce your frontal area a bit and make an air dam less needed. So it would probably be the best overall thing to do, but at what cost in ride, parts, labor, and handling performance? Spending thousands to save hundreds does not pencil out in my book.
