We did Kinsale to Galway a couple of years back via every peninsula and had a fantastic time. Kinsale is a lovely place to stop so I can highly recommend that rather than Cork.
The Smugglers Inn in Waterville was also really nice with a fantastic restaurant. Crottys in Kilrush was interesting as you're staying at the pub. Handy!
I've got GPX routes somewhere if you'd like them?
Overall it's absolutely stunning and a fantastic trip. The Connor pass is apparently fantastic when the vis is greater than 50 metres which is what we got...
