Hi all is it possible to connect an Xbee directly to a APM2560 without using the IMU Shield? If so how do I go about it?

Yes it is possible. The telemetry port is serial 3 and is managed by the 2560. The IMU board just caries the wires up to the top layer.
This is the image from the wiki, of the 2560 upside down. The markings will guide you to the correct pins, then you flip it over and find the correct place to plug in on the top.
In the top left you see TX3 and RX3, the "telemetry" port lines. Those are the two serial lines that are passed "up" to and through the IMU board and used for the Xbee or other telemetry.
You can simply connect pins directly to them. You will also need power, so pick a GND and +5V line from either side of the board, I have marked the two locations. As you can see from the picture, the GND and +5V markings are printed on the board, so you can make sure you connect them correctly.
Those are the only four lines you need for an Xbee. Make sure you arrange them in the correct order. The Xbee board is also marked.
