In the CO, you'd have Eibhlín Dhubh and Róisín Dhubh : the dentals' rule applies with nouns, not with adjectives (in the CO). Looks like the dentals' rule applies very often to adjectives too in Gaeltacht speech.
About "teilifís fón póca", I don't even know if you should lenite póca or not ; normally "fón" should be lenited but I guess it isn't because it's a loanword (you don't easily lenite loanwords that begin with f, for example I called = fónáil mé, not d'fhónáil mé).
My grammars don't say if the third noun of such a phrase would be lenited or not...

These are right.
About teilifís teagaisc, you don't lenite the t because it is a dental consonant (and teilifís ends with an s).
What is teilifís teagaisc by the way? A teaching television?
