Your data comes back via the GPS's UART port.
Use the softserial library to create a second serial port on your Arduino (means you can still use the normal serial to read the console).
Then write a program that sucks data from the GPS and squirts it out of the Arduino serial port back to your PC using printf.
I only had a quick flick through and didn't see the default serial speed, so start with 9600 and experiment.
What should come out is probably a line of comma separated values which is in NEMA format. Google for the specification and you will be able to find out the bits of interest.
Hope that helps.
