No. If you bought your flights in a single transaction as a single contract the flights are on one ticket. You may obtain different PNRs (or references); this is just because several computer reservation systems are involved.

I would not be confident but EI are pretty bad at communicating with their codeshare partners. You may even get points for the EI sector you don't take.
Your bags will not travel to DUB without you: even if they are tagged to DUB, you can insist that they be returned to you at LHR if you like. It may take an hour or two to retrieve them.
