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.
