Interfacing to UART (1, 2, 3 etc) on Mega

Hi, I am new to the arduino but have jumped in at the deep end.

I have a Mega 2560 board and would like to use one of the extra UART ports to output debug messages.

I have a UARTSbee adapter, is it simply a matter of connected the TX to TX - are these logic level signals ?, do I need to swap TX and RX so TX on the UartSBEE connects to RX of the Mega ?

Thanks for any help

What is the USB connection (to Serial) being used for? In general, it's easier to connect peripherals to Serial1, Serial2, or Serial3, and leave Serial for debugging.

A what? Post a link.

I am using an XBEE on a IS Shield, so its using the the standard serial port already.
