A few quick items:

If these gps's are ttl serial, then you can use the 2 uarts in the pic.

Second, if you dont need to realy send anything from the PC to the pic, you can use any available I/O pin to send serial data to the PC. you will need either a ttl 2 rs232 chip, or ftdi usb-serial_ttl cable

The rest is pretty straight forward, just read the example serial drivers.

Mike,

I highly recommend you run a spell checker on that website of yours. Lots of mis-spelled words!
