I'd second @withered_preacher on the slightly darker roast, especially at a wedding (the majority of people are gonna want milk/cream/sugar regardless.) I often make Red Brick as a filter if it's for my family as I know it's still going to be a million times tastier than what they're usually drinking.
Amounts wise, if you can find out how many litres that thing holds, it'll give you an idea of coffee. Usually between 60-70g per litre.
