Sail and Rail is the cheapest route for sure. It's usually a flat price.
You can base yourself out of somewhere in South Dublin and do a lot of great rides in the Wicklow Mountains. Much more accessible than anything in London, and not too much traffic because the area itself is largely unpopulated. Cruagh or Stocking Lane are the traditional entryway climbs into the mountains, bringing you up to the Dublin/Wicklow county border. You should be able to find plenty of Audax routes in the area for some challenging rides.
The most popular cycling route/event in Ireland is the Ring of Kerry. However, it's a one-day event with road closures, and I really would not recommend riding it on any other day of the year. It's a very busy tourism route that's barely 1.5 lanes wide at the best of times and typically filled with tour buses.
There's a very long thread on boards.ie about cycling the grand canal, usually with frequent updates of the greenway progress. Haven't kept up with it lately but would be worth checking.
