But the problem is with tweaking global image sharpening parameters increases the amount of visible noise in your images. I keep them zeroed out, by default. Due to the high quality lenses I work with, I find images from my K5II inherently need less sharpening.

That is unusual indeed, there may be something wrong with your camera settings or something physically wrong with the camera itself.
Considering all these manual focus lenses you are using, are you by any chance using a third party focusing screen? They are well known for causing issues with AE.
Out of curiosity why is that?

I personally haven't had any issues with the Manual metering on my K5IIs - but then again I'm using Pentax lenses, third party manual lenses might not have linear aperture mechanisms and this might be the cause of your exposure issues.
Low light metering is difficult, and a metering system attuned to 18% grey isn't much help with high contrast scenes. Have you tried shooting with you lenses in ordinary daylight, does the problem persist then?
