The biggest worry I'd have from reading the above is that you haven't got the accommodation locked down.
What often happens (it's happened to me many, many times over the years) is that a lot of the central, reasonably priced accommodation gets booked out, especially if you're visiting hotspots/busy towns or villages.
You then tend to get stuck away from the action.
So, you need to lock your itinerary down and get booking. Some tours (e.g. Kilmainham Gaol and the Skelligs) book out well in advance. It can be also far more cost-effective to book online.
Here's a bit of help, as requested (I've taken into account that you want to see a good chunk of Ireland during your visit. On certain days, there'll be a good bit of driving. If you're the type of traveller that doesn't mind just getting stuck in, then this shouldn't phase you):
- Day 1: Dublin
Things to do:
- Take the DART out to Howth and do the cliff walk (leave the city EARLY and do this)
- Grab a post-walk bite to eat then in Howth Harbour
- Take the DART back into the city and head off in the direction of Trinity College (do the Book of Kells tour)
- Take a bit of chill time and nip into McDaids for a pint (great Guinness and a proper old dublin pub)
- Walk to O'Connell Street and do the Witness History Tour (all about the 1916 Rising - excellent tour)
- That'll give you a good mix of the city and a taste of the wider countyDay 2: Wicklow
Get your rental and then:
- Visit Lough Tay
- Do the Sally Gap Drive (starts from Lough Tay)
- Get a coffee in the Wicklow heather (gorgeous spot)
- Drive down as far as Glendalough (parking can be a pain, but you'll manage)
- Do the spinc loop walk if you're active (4-5 hours) or just walk around the lake
- Head for Redcross and do the Wicklow Brewery Tour (you can also spend the night here - it's a place called Mickey Finn's)Days 3 and 4: Cork
I'd spend day 3 in cork city and then day 4 spinning around west cork.Day 3: Cork City/near the city:
- Visit Cobh
- Take the ferry to spike island and do the tour

I had two cups of coffee while typing that... it's a bit of a brian dump, so apologies!
This really is a flying visit to a lot of places, and it won't be for everyone.
A shamless self-pug: if you're looking for inspiration on other things to see, I've written a detailed guide to 113+ things to do in Ireland
A good chunk of them are off-the-beaten-path.
Definitely try and get your itinerary locked down, though. The sooner you get it done the sooner you can stop stressing and actually look forward to it!
