"Is there a single place that lists surgeons' success rates for hip resurfacing specifically and what variables go into determining the score?"
No.
Seriously, how could there be? This would require every surgeon reporting every surgery to some master database, not to mention the issues of determining success in the first place.
That db you mentioned is a case in point. It is based on insurance data (Medicare, so data specifically on a subset of patients that are elderly and/or disabled) regarding rates of complications. It tells you nothing about eventual patient outcomes. IMO it's utterly worthless for judging the quality of a surgeon.
Hip resurfacing, as opposed to THR, is such a subspecialty that only a relative few surgeons perform it. Several doctors publish studies of their own patients that you can find online, but nothing for everybody.
