In the mean time, I'm going to play around with the location of my vTx (200mW power) and cloverleaf antenna....get them down and away from the GPS antenna as far as possible.

Also, what is your opinion on using magnetic field shielding as a GPS groundplane?

Magnetic fields are not an issue with a GNSS antenna, that would be the case if you were using a compass, even in that case, it would be a bad idea, it would cause more troubles than benefits because it could disturb the earths magnetic field more than other conductive materials. A PCB board painted with permanent marker to match the craft style is my easy choice. I recommend you a GPS+GLONASS for faster fixes, not only GPS antenna.
