As for #3: I believe you have to use Leap of Faith or Abundant Step.
Designing a chest which excludes half of your players isn't cool. Being able to use cannith boots is good, but there's still a problem: it seems 'you have to' still be caught by the trap in order to land one of the jumps. Not all of us are caught by traps.
I'm not saying it should be easy. It just shouldn't be exclusionary.
