Duplicate cards automatically go toward increasing the max level of the cards - so you will basically never have duplicates. To "Idolize" a card, you spend jewels on the idol road until you get to that particular bonus. It's usually behind a level requirement so you'll have to level up the card in lessons too before you can idolize.
