    1818I would recommend using a support for the oscillator so that you can easily  change it (I used a 3.58MHz one and a 6MHz one for testing).

    1920I did include any LED or anything that was not absolutely needed.

    2022JP1 allows you to select between 5V and 3.3V operation, this can be useful for cards that needs a 3V power supply instead of 5V. If you use 3.3V you will need to find an oscillator that runs at 3.3V
