I thought I had heard them all, but your description of the t-case lever made me literally bust out laughing.As others have already said, it's normal for both the oil pressure to fluctuate and the t-case lever is as stiff as a ministers dick when new.
I'm also a proud 2.0 turbo owner. These turbos are liquid cooled with antifreeze which is very efficient in helping the center bearing shed heat. They are still lubricated with engine oil, so it's still advisable to avoid coming in hot and heavy and immediately shutting it down. Turbos that rely on the same lubricating oil to also shed bearing heat are what really need a few minutes of idling before shutdown. Oil isn't as efficient as a coolant, so it takes longer. Also, oil flow stops with the engine, so the oil trapped in the turbos bearing housing will "coke". This means that the liquid part of the oil sizzles off and leaves carbon deposits along with any heavy metals and other contaminants that were suspended. This abrasive builds up over time and leads to premature wear and failure of the center bearing and impeller shaft.
And yes, I've never owned a turbo, but I remember the horror stories about the bearings in the earlier days.
