The quickest and easiest way to rid your self of smog equipment is to hike up your britches and start yanking anything with a vacuum hose attached to it.  Be brave, because at first you will second guess everything you should remove, but keep in mind that YOU DO NOT NEED SMOG EQUIPMENT FOR YOUR ENGINE TO FUNCTION PROPERLY!

Below are items that you can start to tear into first. 

Counter clockwise from the top left circle:
-EGR Vacuum Module and Outer Vent Control Valve
-The pesky hard vacuum lines (remove all the vacuum lines attached to it too)
-Thermo switch
-Air injection piping (on the exhaust side of the head attached to the headers)


From the far left Circle:
-Vacuum switch (the High Altitude Compensator will be in this area too if you have one)
-VSV
-Reed Valve
-BVSV (attached to the center hole in the  intake side of the head


Here is a shot of a rough desmogging prior to my rebuild:
