Increase the horizontal scale to 20 milliseconds per division and the horizontal scale to a lot less to get more resolution on the pulse height.
What are you triggering the 555 with? If you are using a pushbutton switch you should press very quickly and see a nice square wave (the waveform should return to zero once you have the correct horizontal time scale).
Not sure on the output. You would just disconnect the output pin from the circuit and measure that directly with the scope.
Is the scope set at 50 ohm input termination?
