Excellent video! Your bike is absolutely gorgeous. I still think the 1800 is one of the nicest looking bikes ever made...and yours is detailed beautifully...
2 gaskets are required, but just one for each cylinder, it appears they just reused the old ones. I would not put new gaskets over top the old ones, as it will typically leak. And you risk bending the exhaust flanges
I have not, the exhaust itself looks like its a larger diameter, but really its a heat shield that gives it that appearance. Pretty much all the chrome on this exhaust is heat shield. it gets hot but it never like actually has melted anything, I'm sure if you left something on it long enough it would, but in my experience I haven't.
