First, does the shifter go through all of the gears with the engine not running and no clutch pushed? If so I'd say the clutch is probably all used up. If you still have oil pressure "the same as before" , the engine is probably fine if it was a very short run. Be prepared to catch some flack for the Frame filter. Most don't use them. It's your choice as it's your car. As far as AutoZone, I'm surprised they went as far as they have already. It's your responsibility to make sure the parts are the same before installing. Probably not what you want to hear, but it's what I expect them to say.
