Blackest night/sinestro Corp war

I'm curious how much of the two mentioned story lines are canon in current DC comics. Are superboy prime, anti-monitor and all the events still to be considered as happening more or less the same way?
If superboy prime exists then infinite crisis is canon?

I am not up on the new reboot but I'm trying to wrap my head around it all.

Anything Geoff Johns wrote while head writer of the Green Lantern books is pretty much canon, at least to the Lanterns that lived through it.

As far as Prime goes, though? No idea.
