I've never had a pork steak that wasn't sauced on the grill then placed in an aluminum tray full of more sauce until eating. They are a staple of backyard cookouts around here so I've had them cooked almost every way imaginable and they are all pretty good if they aren't overcooked. They are super cheap so buy a bunch if you can find them and just experiment.
As for the beer, sometimes people will use it in their sauce but I wouldn't call it "the rule." If you are gonna use it, at least make it a Busch heavy.
