VZ clutch change, help

[Rileymax]

So I bought a second hand exedy clutch and flywheel, all I need now is to get the throwout bearing for it

this is where I have no idea what I'm doing. on my old car it was just a bearing on a shaft and now I'm being told about concentric slave cylinders and whatnot
is this what I need?
