So, where should it go? I have a preamp, and this complicates my selection. - After the antenna but Before the Preamp Box?
- After the Preamp Box but Before the Preamp Power Inserter?
- After the Preamp Power Inserter and before the TV Tuner?

First choice would be on the input to the pre-amp PROVIDED that you have your pre-amp's case grounded as part of a contiguous and unified grounding scheme (single continuous wire running from the pre-amp case to mast to grounding block to structure's ground electrode system).
Second choice would be to install it on the antenna side of your grounding block and be prepared to sacrifice the pre-amp.
Most in-line coaxial surge suppressors work by diverting surge current from the center conductor to the coaxial shield. If the shield is not properly grounded with a low impedance path to ground, the device will simply shunt the current to the shield and the current will find its own path to ground, most likely through your indoor electronics equipment.
