If you don't have the cable, an arduino uno also works as a usb to serial adapter.

To make 3.3V out of 5V you can use a voltage regulator.

If you want to do anything even semi-reliable with this thing you'll want a regulator on the board anyway. Wall warts are notoriously noisy.

This. New switch mode ones are crappy, really crappy!

I have a stash of old linear ones that aren't fortunately. Worth their weight in gold.
