If you drive the Ring of Kerry, go counter clockwise and you'll avoid oncoming bus traffic.
Temple Bar district in Dublin is where it's happening at night, but very touristy even for Ireland.
Skip the Guinness "tour" and visit a whisky distillery instead. Guinness is a tourist rip-off while the distilleries let you get up close and sample.
I found that Killarney had more interesting and entertaining Irish folk music than Dublin.
If you see something you like at any of the many gift shops, don't count on finding it cheaper elsewhere. It seems like the Blarney Woolen Mills and Quills are in every town and they set the price on souvenirs and other things Irish. The good news is that if you forget to buy it in Dublin, you'll find the exact same sweater, hat or doilie in Kilkenny, Cork or Limerick.
