Kinda sad that I had to ask here (and some colleagues) to get that information. Asked in Edgeworthstown, Connolly (at the information desk no less) and Longford.
The answers were (in order):
1): Leap card?
2): Call taxsaver (sersiously, the only way that guy could have been any more disinterested in helping me would have been if he'd been asleep).
3): Incorrect information (it was my wife who enquired in Longford so it's second hand and they did at least have some clue and try to help)
