Yeah, this site is pretty good for LQ1 info. Only other place that would be a good source for LQ1 info is the Fiero forum, they like to use the LQ1 in their cars. I've actually seen one of em make a custom intake for their LQ1.
All LQ1 cars are rare now. Z34s, GTPs, Cutlass Supremes.
It shouldn't but there's always a possibility. Amistydj grenaded his 95 LQ1 engine redlining the hell out of his engine. Of course in his situation he had a bad pulley and that might have made a lot of difference in the situation.
I however also had this issue before (timing belt breaking) on my 94 and it survived even though it was hard as hell to time it.
TLDR, LQ1s usually don't grenade themselves if they don't interfere however it can always happen.
