I should have been more specific. These parts have NEVER been changed since we've owned the truck (since 96) So IMO its worth it to buy a new part, check it and replace it then to go through the trouble of testing these old units that are known to go bad on these trucks, since these pieces are now 14 years old with heavy use and abuse. However I completely understand what you're saying and appreciate your advice, (I will definitely test my new parts, that something that I don't normally do) and I thank you for all your help so far!!

Either way, in about 3 weeks I'll have all the time in the world to do this when the 72 is running and I'm out of school for the semester, so I'll prob tear apart the truck then and check my parts/test my possible new parts then.

As of right now, the codes are telling me that my IAC, O2 Sensor, TPS and EGR are possibly faulty. That narrows down the list. We changed the 02 sensor a few years ago when we put the new headers and Y pipe, but I remember something being sketchy when we did it. I'll have to check and make sure its hooked up since the computer apparently is getting no response from it.
