Balor? Isn't that just something that was made up to avoid getting sued by Tolkien's estate? As such, it might be pronounced "Napolean Bonaparte" for all I know (though I've always pronounced it "Bah'-lore").
EDIT: Just found a reference to Balor in Irish mythology, but no pronunciation guidelines.
Like you said, Balor comes from an Irish root. Given the Irish etymology of similar words like "bane" and banshee from "bane sidhe", the long 'a' seems to be prevalent. Also, because they're nasty bad things, pronouncing the long 'a' immediately brings "bane" to mind, meaning, of course - bad.
"Drow" has been argued back and forth, but official (as official as you CAN get for a fictional word) sources seem to stick with "cow" rather than "show".
"Svirfneblin" just seems instinctively phonetic, somehow.
