A few ideas for Ireland. Ring of Kerry, Dingle peninsula, Rock of Cashel, Muckross House, Trinity College in Dublin, Killarney, the pub in Dublin owned by Bono of U2. Look at Rick Steves site for more ideas.
I like Gravati shoes. Very good quality and very Italian style. They mold to your feet after wearing them a few times. The peccary leather on those shoes is great. I would wear those with a suit as I think they are a classic style but I am not 30 anymore.
Go with a light blue shirt, dark brown tie and dark brown shoes. The shirt and tie you have look bland with that suit. The shoes are too casual for the suit. Get some dark brown dress shoes with leather soles.
