Fellas, quick question. When you do a compression test with that tool you get from the auto parts store. What compression on the gauge tells you its good? I'm going to do a compression test with one on an Aristo motor. I think the factory compression is 8.5:1. Is that what im looking for on the gauge or will it read something else?

You will read PSI on the gauge. IIRC according to Toyota FSM the pressure should be =>155/160psi and pretty even on all cylinders (+/- 10~15psi).
Hope that helps.
