I think the OPs question is does he have to apply for citizenship at a cost of well over €1,000 or is he actually already a citizen based on his long standing residence in the country.
Every citizen is entitled to a passport cost €80. The question of who is a citizen is unclear. With respect to Socrates his links are about how those who are not Irish citizens can become so.
It appears that the OP is not an Irish citizen and would have to apply for citizenship and the cost involved.
