Meter carefully. watch for shiny highlights.
better to slightly over expose then pull back in post processing.
here you'll find a couple examples I did recently:

the best technique I know of for dark skin, involves polarizing your light source and a polarizer on your lens to have control over highlights, which probably is goin to far for your needs.
if you got lots of natural light, use it and a reflector, and maybe a little (set to manual powered right down low) flash for a catchlight in the eyes...
JR beat me! note : JR is correct for shooting jpegs, I shoot RAW and do post processing in Aperture and Photoshop...

I own a motorcycle, I get spots with rings like that on my my bike (esp the saddlebags when traveling) after lubing the chain...

DCUK's caption for the image was "Please note the fine white marks are the problem area, the bubble effect seen below the marks, is out of focus reflections from the light."
that would IMHO mean the white spots are on top of the aa filter, in order for there to be distance to create the shadows..... still could be particles clinging to oil droplets on the surface.....This is the photo I'm talking about, which clearly no one else has seen

I don't think that's right. If you go back and look at the macro photos that DCUK took of the sensor, it clearly shows the offending blobs are actually particles of some sort. The ring is just the shadow.

I think there are two different issues here one is easily fixable.
One issue is blotches or stains UNDER the aa filter the other may be lubricant flinging off the mirror hinges onto the aa filter.
whatever they lube the moving parts with has to be very light and susceptable to flinging off, a heavier lube won't fling, but will generate friction and impede the speed at which the parts move...

Maybe Chris at SRS can try this out for me...
Take a new k5 that does not have this problem from the package....
then fire off a lot of fast shots in continuous shooting... then check it again for spots. Oil flows best when warm, so do it in a warm environment please.
looking at those photos, many of those dark spots appear to have faint rings around them...
like you'd expect from a fluid, or lubricant.... then the next question is where did it come from, and is it permanently eating into a coating on the sensor or is it simply a matter of using a cleaner that will lift of the oil but not damage the sensor...

look at the dark skinned subjects carefully and you will see a patten...
to seperate a dark subject from a dark background, you need a separation light behind the subject pointing towards the subject.
you could do black background and use the flash to seperate the subject from the background, then reflectors to bounce light on the subject.
