IRELAND DRIVING PLAN AND ITINERARY : 9/1-9/16

Would love ideas/feedback after having read all TRs I can find as well as travel books. We are seasoned travelers, but this is our first trip to Ireland. We don't mind long drives with beautiful scenery. Love historical places and the outdoors.
Mainly, we have questions about early part of trip: how many nights for Antrim Coast (1 or 2)?
also, any changes to overnights on way to Galway?
we are driving Connemara, visiting Kylemore on way south and via Clifden/Doonlough valley
