Correct, this board does not model the raspi USB controller yet,
and networking on the board is connected via USB, so none of
networking or USB keyboard/mouse will work. The raspi hardware
also does not have PCI so the QEMU model doesn't support that
or virtio (which is usually via PCI).

You can't currently. You can use the graphics for output and
the serial terminal for a console.
