Not orbit, the Moon doesn't orbit the Earth in one day, but a month. The cable would be almost stationary compared to orbit. That needs less power.

  Less, but not much less. Around 12 km/s instead of 14 km/s.

    Escape is 11.2 so something must be off. Edit: actually you don't need any specific speed. Reaching orbit does, around 9 km/s for low orbit, vertical uplift doesn't.
