Canon 1d Mark 2 - Need some help

[newbiec]

I have been thinking about buying my uncles Canon 1d Mark 2 since he just recently upgraded and is wanting to sell it. He is letting me borrow it while he is on a cruise so I've played around with it a little. I've noticed that if I take a picture outside, they are overexposed and its difficult to make out what the picture is even of. Inside, without a flash, is extremely dark, and again, difficult to tell what the picture is of. Inside, with a speedlight 580 EX 2, the photos turn out fine. What am I doing wrong that the pictures turn out terribly when either outside, or inside without the flash? I've tried so far with a 70-200, 50mm and a fisheye lens, and they all produce the same results.

Another question I have, the back screen, is it possible to view live shooting on it?

Any information would be great, I don't have the manual and my uncle won't be back for 9 days.

It is definitely user error. Thats an old camera, I doubt it can do live view.
