Q2: If the 3 cards I reveal from my deck for this card's On Play effect include both a card with Puppet trait and 1 card with the LIBERATOR trait, can I choose to only add one of them to my hand, and place the remaining cards at the bottom of my deck?
No, you can't. If you have cards that are targets of this effect, you must add as many cards to your hand as possible.
