Wow that car is beautiful! My first car was a 73 Fury III two door 360 2bbl. Since you already have the carb & intake I suggest a true dual exhaust and rear end gears. Assuming it is an 8-3/4" then you could run 3.23, 3.55 or higher. It all depends on what you want to do with the car and how much money you have for expensive Israeli gasoline. 3.23's are probably a good choice and easier to find + don't forget to change your speedometer gear. You might also consider a K&N air filter in any cheap air cleaner you can find (open of course). You don't have to replace the ballast resistor, just keep an extra one in your car. If it won't start all of a sudden, that's most likely the problem (they burn out a lot)
