If a dreadnought is transported in a superheavy with firepoints may it use they firepoints to shoot in the shooting faze? If it can, how may weapoons may it fire?

Nope.

The rules only have the option for Infantry to fire from vehicle fire points. There are no rules allowing any other unit type to do so.

Unless you are an Ork Dreadnought in a Battlefortress for example. It specifically states all embarked models may fire.
