No - Irish operators do not require any passport when purchasing SIMs or phones. I am not sure about top-ups with US credit-cards, however - but you can always buy top-ups in a store once you are in Ireland. Make sure to choose a reliable network operator. Stick with Eir or Vodafone - they are the best. Avoid Three and all the MVNOs that piggy-back on their excuse of a network.
