Don't be in such a hurry to replace the headst & stem. It would also require a new fork. To save a couple bucks you could use a threadless adaptor with new stem, original fork & headset.
Good luck, The World Sport should be a nice solid bike, a fun project and a great learning experince.

'cept I wouldn't necessarily replace the chain. Unless totaly rusted out, chains are easly to rehab. Drop it in a milk jug half full of kerosene, agitate, and let sit for a few days. Agitate every once in a while. You'll be surprised how much crud will come off, and even rusty chains can be reclaimed in this manner.
