    In this case I would just test the serial communication with the GPS chip with a terminal emulator, like Tera Term Pro or Hyperterminal, connected to the Shield. I just did that with the EM-406A (using the uUSB-MB5 - http://www.sparkfun.com/commerce/product_info.php?products_id=8531), and saw that the chip keeps sending NMEA strings, even though I am inside and cannot receive GPS signals. This way I am sure that the basics works, before introducing additional layers such as GPS API etc.
