Well, I'm at a dead end and could really use your help. And, just for the record for some of you this may be a "baby" question but I ask you to bear with me anyway as I really don't understand what's happening.
Question - how can you overexpose your highlights when there isn't enough light to properly expose the image (please see below)?
(All I did to this image was remove the noise and add a sharpening mask as it was blurry due to my hand shaking at 300mm)

As you can see the yellow flowers and his white shirt highlights are blown out. But, I shot this at f/5.6 (the lowest for my zoom at that focal range), ISO 1600, and my exposure compensation was at -.5 (i.e. -1/2 stop). I shot everything on aperature priority.
Whenever I exposed an image without using the exposure compensation all of my highlights were blown out. But, from where I was seated the fastest shutter speed I could acquire was 1/60th, most shots were at 1/30th, @1600 ISO. The "properly" exposed images were blurry (i.e. 1/15th - 1/30th shutter speed and a moving subject) and the highlights were severly blown out.
Clearly there is something "basic" that I don't understand about highlights or low-light exposure or f-stop vs. highlight relationship that I need help with. How could my highlights be blown out when there wasn't enough light to properly expose the image? I hope I've explained myself, please help me - anyone?
