If the tank is galvanized then it don't need painting. As someone mentioned in another post IF you do paint it rinse it with vinegar. I personally would leave it along.

There should be no need to put something under a new gasket as long as its tightened properly. Some gaskets are cork, some are rubber. Most re-pop are rubber unless you order the cork ones. Just depends on the site/vendor.
I don't think paint, one way or the other would hurt as there is no gas getting to the paint unless the sender is not tight. But, if you paint, it could effect the ground which is the most common problem with guages these days.
In short, I'd not paint the tank or sender and I would make sure all/any connections are tight with new seals/rubber. A new gas cap is also in order. You should not have a gas smell problem.....except maybe right after you fill up for a minute or two.....all this is my opinion, and what I do with new tanks.
Whew, this got to long.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
