Do you ever use "I'm after Xing"? I have various reports that that construction is still current, at least among speakers of roughly my generation or older.
I don't think I use it a lot personally, but certainly phrases like "I'm after doing/saying it" doesn't sound strange to me at all, indication that I hear the phrase pretty regularly. Phrases that spring to mind are, "I'd know" presumably from N'fheadar, and people go in funerals and weddings. Looking at the Wikipedia article, I often end sentences in "isn't it" or "doesn't it" or yeah or no depending on the answer I expect. Or, "I'm doing the right thing, amn't I?" Shur, or ahshur and those sort of interjections are extremely common, and I never realised that "this one here" or "that one there" was an Irish phenomenon. Also, bring and take seem to correspond to what wiki says is the Irish way. Ye is what I would use in speech for the second person plural pronoun, and yere. "I've my homework done" sounds perfectly normal to me too, is that not so for other dialects? And the myriad of insults and terms of endearment, I'd certainly use some of them, but the others are probably limited to older generations. Messer, Plaidhce, Rogue, Amadán, Oinseach, lúdramán, craytur, mo ghile, mo ghrá. Then plamás for nonsense or enticing hollow words.
