Congrats on making the move! My wife & I are about to "learn" our way through our first winter as fulltimers here in South Central Kansas.
As for question # 1
The straw bales will certainly help keep the harsh winter out from under the trailer, when winter fully kicks in with sub freezing temps I doubt just a single bulb is going to help much more than the bales of hay are already doing. The Air space underneath is too great and the bulb will do little to radiate much heat unless it is literally up against the bottom of the Airstream. ( on the other hand, it certainly cant hurt)
There is a simple way to run just the furnace fan. (however my knowledge of Airstream furnaces is kinda limited to strictly our particular model)(maybe yours is similar)
Look inside your furnace access door, you should basicly see the blower motor, the gas valve & igniter, relay, on/off switch and a small control pc board.
Pulling that connector with the white, red, yellow wire off the board allows our furnace fan to run with the control off the thermostat inside.
The only downfall is if you decide you actually want to run the furnace, now you have to go back outside and plug it back in.
There are ways around this also. But I'll leave that to your own ideas.
This is what I'm going to be "experimenting" with here when it finally gets cold enough.
Hope this helps. Let me know what you find. Todd.
