By now you have checked out the sites on the internet.
I have done some climbing in Ireland but different county than where you mentioned. I climbed in County Kerry at the Gap of Dunloe near Killarney. Wonderful friction texture to this sandstone rock climbing.
If you happen to get to Killarney, it might be worth a twenty minute detour to the Gap. If you do, just ask the bartender at Kate Kearney's Cottage for the house copy of the area climbing guide. And don't forget to order a pint of Guinness. Even if you hate the import, it's likely you'll fall in love with the real thing.
Also Carrantuohil ( Irelands highest point) can be a fun non-technical day.
Last note is to bring bug lotion or whatever to combat the local flying scourge: the midges. They are vicious.
