    1. The caps you should keep, they ensure the voltage on that line stays constant without ripples. The ESD looks like a nice to have, you could omit if you want.
    2. Yes they should be on both halves
    3. It looks like you can mount the ESD chip on the bottom of the right half. Pins 1,3,4, and 6 do the same thing, so the ‘data’ line going into it can go into any. Pins 2 and 5 need to be ground and VCC, respectively.
    4. The ESD circuit is protecting the rest of the circuit from spikes when you plug in the jack. You might be charged, and if you’re touching the metal when you plug it in you’ll discharge into the circuit.

    Hope this makes sense!
