If that brass tube on the front of the water pump you mention is coming out of the bearing drain hole don't worry about it. I recall hearing something about them adding a tube for drainage after a bearing failure to keep from making the engine compartment messy by the coolant getting on the belt and flying all over. Also that gasket info is great, I use the same guidlines, I did find however that the gasket provided with my water pump was made of rubber, it was just a rubber o-ring so I didn't use any sealer. When it is rubber I don't use anything just make sure surfaces are clean and even like mentioned before. I am not sure about the water pump on your car though. Good luck!
