Dave, I've just upped the contrast a little to get the skin tones closer to what I think you're after. It's probably just on the verge of blowing out, and as far as I'd be personally happy to go.
Working from this basic shot, you could do some careful local cloning around the eyes and darker spots and at least you'd be cloning from unblown areas. I'd set the clone tool opacity quite low and build up gradually to the tones you're after. It' s a pig of a job to do well, but you'd get a better result I reckon.
You really need to deal with that shadow to the left of her nose. It was ages before I saw it, but then it's like an eye magnet.
