I would like to know what shield pins you are using for the board; I want to use an Ethernet Shield along with an Arduino Uno for easy networking connectivity

Ethernet Shield pin usage can be found here: http://www.arduino.cc/playground/Main/ShieldPinUsage

Looking at the board schematics in the documentation, it appears as though pins D2 through D8 (step/direction x3 and enable) are used along with the Ground, 5V. Are there any other pins used?

Thank you

You are correct. Pins D2-D8 are used as you stated. 5v and ground are also used but unlike pins D2-D8 you can use them for other purposes as well. Note that the V1 board uses the 3.3v supply instead of the 5v supply.
