Black
Yes, a medium ash brown hair color should cover a previous orange color. Since blue neutralizes orange, it's best to use a color that has a blue base.
brown
Yes you do. If you just applied orange on top of the existing brown color, you couldn't see the orange, the hair would still look brown.
It depends on your hair color. This is just my opinion, if you have black hair or red hair, I don't know what color. If you have brown hair you should get blond highlights and if you have blond hair you should get brown highlights.
You say, "Should I colour my hair brown?". Geez.
Bornean Orangutan are brownish orange with red undertones. Sumatran Orangutan are mostly brighter orange in color.

I turned my hair orange! YUK! Anyway, buy a hair dye that looks like the color you want it to be. You might try Light Ash Brown. It's a nice color. I think it's made by Prefernce by L'Oreal.
You should dye your hair: brown, black, a neutral blonde, or even if you have the right skin tone red.
