How do I get an xbee to upload a scketch

1 Arduino Duemilanove ATmega328
1 XBee shield (XBee Shield) KVC mcukit on top
2 XBees (XBee 1mW Chip Antenna - Series 1) s1's
1 USB to XBee serial board (USB XBee Adapter)sparkfun(not sure.. small)

The setting are from Sean Carneys website.
Does anyone know if the USB tranfer sizes in the port setting on the PC matter?

I'll keep trying
Thank for the help.
