Okay..I rented the game but I still know how to get the red tunic (Goron Tunic).
To get the Goron Tunic, go to Goron City after you defeat the Forest Temple (you beat it after all, didn't you). In the place where the big goron was rolling around, there is a small one. Stop it with a bomb, and talk to it a little and it will give you the Goron Tunic. (Its name is the same as your name, its the son of Darunia...but Darunia doesn't have a wife! That's odd...)
Anything from that back I can help, further on...I need to get the game.
