check 02 sensors?
Can autozone check 02 sensors to see if they are bad? I have heard this, but want to know from you guys before I go there sounding like an idiot.

The best way to check the O2s performance is to watch them switching on a diagnostic scanner. I have seen some O2 testers but not at AutoZone.

This is a link on testing O2 sensors: http://www.picoauto.com/applications/lambda-sensor.html

Your computer checks them regularly. If it isn't complaining by turning on the CEL, the sensors are good enough.
