Somewhere after 100k usually. I've never heard of them outright failing though. Usually just seepage, nothing that will leave you stranded for the most part.

It varies by engine code, but this one was 6.1 hours for oil pump r/r. You still need to add .5 for the w/p and .2 for the tensioner(s). Then you usually add on an extra 1 hr for cleaning since everything is usually a nasty mess. So 7.8 hours. Typical dealer price is around $2K.
They sometimes are. Some folks have speculated that old/worn oil with acids (higher TAN?) will deteriorate seals.

i sold a bmw 745i with bad valve seals to a slimy dealer friend. before he drove off he poured the stuff in. gave him a visit a week later and no smoke at all from the car.
it works, at least long enough to move a car off the lot
I've been told it does by someone who understood the chemical composition of rubber very well that it does work.
Personally, I can say that the BarsLeak oil seal conditioner does work very well. I found a person on a diesel forum that was one of the engineers who created it. He explained in more detail but the just was it was a quality seal conditioner and not a typical barrsleak junk product.
