I don't know how representative he is...

So far as that particular usage os concerned, he is absolutely stereotypical: and the use of "fecking" is just as common in Northern Ireland as in the Republic. It isn't used to such a great extent by older persons with any pretensions to respectability, but among the young, it is used absolutely without hesitation in all situations.
There seems to be no feeling of it being a swear-word, either, merely an emphatic adjective (or adverb, sometimes).
The people who say "fecking" are often quite shocked if a "u" is substituted for the "e",EDITED thanks to eta! apparently treating the two pronunciations as two completely different words.
