hand 1: Dunno if he has a set that much, but some of these guys have AK/AA/KK in their limping range. Without him having seen shoving flops like this, just fold.

hand 2: I would play it the same. He can have JJ, combodraws, sometimes weaker draws...and yes sets. Not much else to do, especially OOP.
Putting people on sets all the time will probably cost you money.
