Hello there, tis an obvious question, but is it Dublin, Ireland your planning to study?? I live in Limerick, but have some knowledge of Trinity Collage, and vast knowledge of the University of Limerick as well as good local knowledge :)
Oh...Galway!! Its amazing!! The city, the collage and the people, and you can find a lot out on line!! My neighbors son goes to Galway...if you like, I would be more than happy to get a few links for you to look at!!
