Overflow plug: 20Nm / 14.75 ft-lbs (incorrectly converted to 27.3 ft-lbs in SM)
Drain plug: 20Nm / 14.75 ft-lbs (incorrectly converted to 7.4 ft-lbs in SM)
I unfortunately used 27 ft-lbs for my drain plug and stripped it....lesson learned. Hope no one else makes the same mistake!

Ouch. I followed the torque specs I had posted and didn't have any issues, but to be fair I followed what was in the guide inside techstream. You are quite correct that the Toyota official instructions incorrectly convert from metric to standard. Quite an oversight.
I'll update my OP.
