I just wanted to know when I put my Arduino in a low power state mode, will the XBee use less power as well, or would I have to put the XBee in its own low power state?

It does use less power when it's not transmitting.  To lower it further you can use the sleep pin.

Would you happen to know what the power consumption is when idle?

Here are specs for the XBee 802.15.4 (S1) and the XBee ZB (S2) low-power modules. The Pro (high-power) modules require significantly more current in transmit mode. See the Specifications in the product manuals for details, XBee 802.15.4 or XBee ZB.

Quote
XBee 802.15.4 (S1)
Supply Voltage 2.8 - 3.4 V
Transmit Current (typical) 45mA (@ 3.3 V)
Idle / Receive Current (typical) 50mA (@ 3.3 V)
Power-down Current < 10 ?A

XBee ZB (S2)
Supply Voltage 2.1 - 3.6
Operating Current (Transmit, max output power)
    40mA (@ 3.3 V, boost mode enabled)
    35mA (@ 3.3 V, boost mode disabled)
Operating Current (Receive)
    40mA (@ 3.3 V, boost mode enabled)
    38mA (@ 3.3 V, boost mode disabled)
Idle Current (Receiver off) 15mA
Power-down Current < 1 µA @ 25°C
