Kill the assassin hiding in the hatch (that's best for exp, and the other one won't show up properly in your quest log anyway).
Kill the frog? well that's a question for your moral's isn't it. For exp and such you're better of killing it (and for reputation too, apparently the game thinks killing innocent animals is a noble deed, as returning the ball will gain you +1 reputation).
That little kid is just going to bore you until you leave town, so deal with it.
And for the key and mirror: just hang on to them, they have a use later on... (although I don't have a clue where that key is supposed to fit)
