Well, I can't read the last attachment, but if you are reading the data out of the unit, I would say you have the serial communication part down.
After reading this: http://eshop1.chem.buffalo.edu/600M-GPS.html it seems to take amplified as well as non amplified antennas. So that's probably not it. How about power supply? Are you giving it enough juice?
This is supposed to be a similar model and pinout, but the board is different.

You might try giving the pre-amp pin 5 volts, if you are not already. This is supposed to give the amplified antenna, its power source. Also, note the frozen start they refer to. They don't even tell you how long it will take out of the box, with old ephemeris data. So be prepared to wait a while to first fix.
