The under belly plate is going to be my project this week. I've been looking at a few ideas. My primary concerns are how I can easily remove it for servicing my vehicle, and the rigidity of the design.

To me, an underbody cover that vibrates in the wind is less efficient than a rigidly attached one, not that I'm saying other designs will vibrate, but zip ties seem like a less-than-rigid mounting system, even if pulled tightly.
I think I've come up with a good plan.
An aluminum sheet (or perhaps 2 depending on how I'll work around the exhaust pipe) attached with hinges with removable pins. Half the hinge can attach to the car's underside with a spot weld, and the other half can be welded to the pan.
Removal is easy, as you just pull the pin from between the hinges and the pan drops right off.

I'll let you know how it goes..
