As long as we are talking soreness and not pain, I would try to go through with the workout as scheduled. I would do my normal warmup of some type of cardio for 5-10 minutes. If I'm really sore, I might extend the warmup a bit. If after the warmup and after doing a light warmup set or two, the soreness is still at a point that you are worried about injuring yourself, then you can abort or modify the workout.
While there are conflicting studies, stretching after a training session has been said to reduce DOMS somewhat. At the very least it will help with your flexibility so I would recommend post-training stretching.
Stretching an already sore muscle however will not make the soreness go away. Also if you are going to stretch prior to training, make sure you warmup first. Stretching is not a warmup and stretching a cold muscle could cause injury, the very thing most people feel they are avoiding by pre-training stretching.
