For what you have now, a full face organic and heavy duty pressure plate will be fine. You can always go more heavy duty, but it's up to you.
I seem to remember that some Hiace (and so probably Liteace) clutches match up, being 200mm diameter and having the bigger 29 by 21 (from memory) spline.
If you plan on a turbo, definitely go for a 212mm fly at least. Though you can always do that down the track.
Any decent clutch place should be able to hook you up with what you need. If they cant, go elsewhere.
