I would take the quilting out. You will never be pleased with the puckers. After removing the quilting, put the quilt outside in the fresh air. You may have to do it for several hours, and see if that will make the top so you can work with it. I have done it to a customer's quilt that needed repairs. It cleared the air and I was able to do the repairs. I would try this before washing and/or putting in the dryer. Good luck.
