I'll get back to you on the substance of your question, but I think you should have a look at the FCOM for the A330. You can download it, or just view it at:-

I haven't got the precise dimensions of the V/S for the A333 series, but am aware that the height of the A332 V/S is about 55cm greater than the A333. The rudder limits are the same, and I am assuming that the rudder area has been varied to match the different V/S designs.
