Configuring xBee radios through Arduino board?

Hello everyone, I just purchased 2 xbee Series 1 radios and have been trying to configure them for the past few hours. Along with the 2 radios I also purchased 2 breakout boards that convert 5V to 3.3 and provide breadboard-spaced access to the pins.

When I remove the atmega chip and connect Tx/Tx and Rx/Rx of the arduino and xbee module, the module still does not want to connect to the computer.
