They effect the amount of toe you would want - the settings above are for the 18" wheels he said he had

Obviously, the toe is also subjective, as it effects speed of turn-in and straight-line stability. Some people are prepared to sacrifice stability for better turn-in (which would be toe-OUT). However, on our poorly surfaced roads, this would cause the car to wander and follow all the imperfections, which is frankly tiring on long journies for a road car.
In fact handling is subjective, so you should really set the car up to do what YOU want it to

thats the thing mate, i'm not too sure what i want the car to do
i want it to drive in a straight line when the wheels are straight
i want it to be able to self centre as normal
but i also want to have the settings so that it goes round corners better than with the factory set up
i've got adjustable tcas and comp struts and i know that i'll have to get the front mounted arb as well at some point but i also have adjustable top mounts (if i can ever figure out hwo to fit them) to go on if that will help matters too
but i don't want to go to coil overs if i'm honest bceause i can't afford them and they don't do a set for the rear of the sierra estate (not that i could afford them then either)
i'm running 205/40/17's at the mo and, as the set up is, they run great until they lose grip and then you get fairly wild understeer but lifitng off brings the nose back in line again and thats the set up i'd like to retain
