Answer 1

You will need to become familiar with the NMEA protocol, which is the format GPS receivers use to transmit data to a PC.  Any GPS device that supports NMEA output could be used for your project.  GPSBabel, which is open-source, supports real-time tracking.  Its code could give you some ideas.
