Either "duit" or "dhuit" is fine here ("duit" is more common in writing, "dhuit" is how it is usually pronounced though)
EDIT: Fuller disscusion of this here

In these sorts of sentence tags the emphatic pronouns are pretty much obligatory.
razlem wrote:Tá mná sa seomra liom (I am in a room with women)
Would that be the right way to write that last sentence?
I think "Tá mná sa seomra liom" is fine. "Tá...liom" can mean "I have...", but I don't see any ambiguity here (even if it was read as "I have" it would render "I have women in the room", which is idiomatic here at least).

Nope. The problem with this sentence is a) you are trying to use the copula, which is used for identification statements, not when indicating physical location (c.f. "ser" and "estar" in Spanish), and b) "leis" is the third person singular of the prepositional pronoun "le", so it wouldn't be used directly with a plural noun, though this form is used when the article is inserted between them (i.e. "le mná" but "leis na mná"). And while "Tá mé i seomra le mná" is not technially
breaking any specific grammatical rules, it is very awkward and unidiomatic. Your first choice was best.
