Here is the dial stringing diagram complements of radiomuseum.org:

On the OT & speaker you can get the plate impedance of the audio output tube and find a universal transformer with a primary impedance close to the tube. That should match to a 3.2 ohm speaker. Don't have any answers for the antenna. If you wait for a junker chassis you will probably wait a long time and then you may have competition. Best thing to do is get it running now and buy the junker if it comes along.
