So, there’s the circular bulb itself, and also this little removable plastic cylinder with two metal feet on it. How do I tell which of them needs replacing, and what specification to look for to know what to replace it with?

Yeah the dark patches on the tube are a sign that it’s failed. If you get a replacement tube it would be worth trying it with the original starter (swap them back) to see if it still works.
