I would pronounce bhfear this way - I have "school" Irish.
I have come to realize that I use both Munster (I actually pronounce the N sound in words like cnoc and cnámh) and Ulster (súgradh as "sue-grew") and Connaught pronounciations, so make of that what you will.
There's a reason that FGB doesn't give pronunciation hints :-)
"tinneas" can mean "pain" or "ache" or "sickness".
"tá tinneas cinn orm" can be interpreted as "I have a sore head" or "I have a headache", but I would read "Tá tinneas ar an bhfear óg" as "the young man is sick", and use "tá pian ar an bhfear óg" for "the young man has a pain".
