Your volume pot/switch is readily available. The on/off + pots are very cheap from RadioDaze.com. You should be able to use their 500K audio taper pot with the added switch option. I always cut the shaft length and cut the flat with a Dremel cutting wheel after installation. Wait for others to add more options to the pot search.
Simply running a "bead" of super-glue around the base of your 6A7 grid cap will hold it very well. When hardened just scrape off any excess with a knife.
A 10' length of antenna is the absolute minimum for broadcast reception; if you have aluminum siding or aluminum faced insulation, you will need to put your antenna out a window and into a tree. 30-60 feet is a good range for shortwave use. Your hum might just go away with a good antenna. If your hum is really nasty, the filter caps will need changing (it's a good practice to change them anyway).
