I agree - ask them to show you studies/evidence that it would be safer for you and your baby to have a c-section at 39 weeks than a VBAC. I bet you it all comes down to hospital policy rather than solid evidence-based research.
Why don't you go to a practitioner right away and have a consultation? They would be the best person to advise you as to when you should start 'induction' acupuncture, and likely they can give you a treatment to help out with any aches and pains you might be experiencing, or at least relax you!
