GPS should be the same for all boards.
TX -> RX
RX -> TX
The pin-config for MAX7456 is the same for most Arduinos, just to mention the most used boards; Arduino Uno, Arduino duemilanove and Arduino Nano (which I would pick).
Arduino mini pro uses pin 9, 10 and 11 - but it doesn't seems like SS is available. It can probably be fixed with another software-version, but I would suggest using Arduino Nano instead.
