if and when your british wife settles and gets a job in ireland , rents a place for you both to live in and can prove that she will be self-sufficient and can support you during your first few months until you get a job , she will then be in a very strong position to rely on her EU treaty rights , and then you should have no problems getting your visa and your residence as an EU family member . ireland will have no option but to approve your visa and then give you your residence permit . please check the requirements for exercising EU treaty rights in another EU state .
your previous immigration history should not affect your application . having said that the irish authorities might and most likely will try to obstruct you joining your EU spouse , but you should ex host all venues to get what you and your wife want because the EU laws are in your favour .
if you encounter any problems of refusal , you and your wife can then appeal that decision and immediately contact" SLOVIT" (they are the european Union body that solves issues that arises between a member state and a citizen of a member state ) here is a link to their website :

wishing you and your wife the best of luck.
