yup, that should be all it is. these engines stop rotating almost instantly and the belt will slip "squeak". Nothing to worry bout.
As for shutting it down right away, If you just put it in drive and granny cruised across your field your fine, after a normal round town drive give it 1-2 minutes, if you just drug a trailer or ran it hard let it sit for 3-4 minutes to cool off then shut it down. You just don't want that already hot oil to be sitting in your turbo while the turbo is still cookin its hard on the turbo.
