TPR and Kaplan say that the heat (Q) and work (W)-on or by the system-is ALWAYS greater in a reversible process than a irreversible process.

help? more importantly, why is this important?

Is not important, its just a consequence of having a reversible process. I don't think that is required to know for the MCAT, I learned about that in my pchem class which is way out of the scope of the mcat.
