Yeah they both use brake fluid, so one reservoir, two different cylinders(one for clutch, one for brakes). I did a quick search and the tC only has one. Even found a good story where a Toyota tech told a tC owner they had two seperate reservoir's, and then couldn't find the clutch one under the hood when he tried to show them, because it wasn't there. So I'm assuming ours are the same. But if I'm wrong, don't worry, someone will let us know.
As for bleeding them, it's probably a good idea to do them both at the same time. Otherwise you might end up chasing a problem back and forth trying to eliminate air bubbles.
