personally i wouldnt cook them in the oven, the boil first method is a good way to tenderize but you lose the meats natural flavor and substitute with a marinade flavor. there are other ways to tenderize without losing the flavor of the meat, marinade is ment to enhance the flavor of the meat not substitute. try taking a vidalia onion, some lemon juice, red peppers, and a can of beer, soak 24 hrs,this will not only taste great but the lemon ,the alcohol , will tenderize the meat for you, now i prefer smoking when it comes to ribs, if your grilling do it indirect heat,do not cook directly over the coals, it will take longer but will taste so much better
