I set my company up as the publisher of the website and for the articles I do write I have set authorship up for. I have been put into 10 Google circles.
I agree with most of your points. With B I was never worried about that and C doesn't concern my sites.
As far as D is concerned I can't say I say a negative or positive affect (been using it for 3 months now). My site is trending lower still but I that is a penguin issue and not authorship.
The only reason I do Google + is because I know Google will eventually use it in there algo. I prefer twitter myself.
