In the April, 2001 issue of Muscle and Fitness magazine in an article by Arnold Schwarzenegger, he says: "Simple soreness isn't dangerous and shouldn't prevent you from continuing to train. But anytime you train through an actual injury and feel pain, you make the situation worse."
He also says: "The only general rule is to not work a bodypart that still feels sore from a previous session."
So, in my opinion, it would be ok to work your shoulders as long as you don't work your pecs while they're sore.
YES! In fact, to get all the lactic acid build-up out of those muscles, start your shoulder day with some push-ups and a set or two of light flyes. Its going to hurt a bit, but this will stretch out the pecs and get much needed nutrient rich blood to that area and decrease your recuperation time. This goes for any muscle that may be sore. It's OK to do a couple *LIGHT* sets of an exercise for a body part you did the previous day for stretching purposes only. If you're sore and not injured, go for it. Soreness won't last forever; a healthy body will.
