You cannot get a magic bar in Twilight Princess. The photos showing the magic bar were in the beta before Eiji Aonuma took it out.
To get it you have to hack the game which is unnecessary considering how good it is.
You do not get Light Arrows or Magic Power in Twilight Princess, so this would be a no.
You don't have to, but you get unlimited rupees and invincibility if you have the magic tunic.
There is no magic for Link. Zelda has light arrows, a sword that can kill anything if she tried and the triforce of wisdom. Ganon has soul possesing(Zant) And the triforce of power.
There isn't an Outset Island on Zelda Twilight Princess only in Zelda Wind Waker and other ones.
Twilight Princess has no MP system. I'm not sure what picture you're looking at (maybe we have different box art?), but there is no way to get magic power like in earlier Zelda games. Don't worry, you won't need it ;)
After beating twilight princess you don't get anything.
