I'll defer to Coach on the boundary phrasing -- he's the best at that.
I will add, however, on the EZ Pass thing: DO NOT reveal the source of your intel! Ever.
Thus:
"I know all about where you went on Thanksgiving, and it wasn't your brother's. Please stop lying to me; it's incredibly disrespectful." If he asks you how you know, tell him "I'm not going to tell you that, but we both know that you lied to me." If he tries to lie to you again, put your hand up in the "stop" motion, and say "Please stop it. We both know you're lying to me right now, and it's incredibly disrespectful to me, to our marriage, and to our family."
Did you print out and save a copy of the EZ pass intel?
