Magnitude/brightness and degree's?

Hi all,
I should know this but keep getting lost.
Is magnitude the same as brightness?
I have worked out that a 0.1 star is actualy brighter than a 0.55 star !
So '0' is the bench mark, is that corect and what is the mark. Not the moon as that is far to bright?

If uranus is 'x' degrees right of Jupiter, how do I work that out??
If I put Jupeter in the centre of my telrad will the small blue/green disk of uranus be inside or the outer retical?
