If we boost before turming the ignition off, does the oil pump keep circulating the oil to the turbos to keep the bearings happy or does the pump shut off, shortening the life of the turbos. I used to let my 87 GN run for 2 minutes min before shutting it off when it was my daily driver.

turbo timers are purely aftermarket products so no. If you drive it hard, let it cool down so your oil doesn't coke.
