Another dumb question... 
Just received an Arduino Nano that requires me to solder on the pins.

Is the extra 6 pin cluster (I believe it's called the ICSP??) on the top side of the board (2 pins X 3 pins) required for the WeatherDuino TX board? If not I can save some soldering!

No, we don't use that programming header as we already have the bootloader installed.
That said, they can be handy if you need to access 5vdc and GND.
