Since he didn't fill you in on how to get those two fusion items, near the very beginning of the Saiyan Saga, when you are goku for the first time, go to one of the cities. Beat General Tao there to get the two fusion items.
Next person: Future Trunks (fighting and sword)
I, personally, like sword trunks better. I know he can't be Super SS, but I still like him better. His sword is the main reason.
