Reindexing is not cheap unless you do it yourself, especially as everyone seems to be scared to do it. It's not necessary though as there should be some adjustment on the eccentric bolts on the rear arms. There's something like 40mm available, but it was there to allow the factory to get the ride height correct and every car is different, you might be able to lower it 35mm or you might be able to lower it 5mm before the end of travel.

Cutting springs is the cheapest option but it's rough as you like and it will almost certainly not enhance the handling, not be even across both sides and will introduce bonging from the struts when the steering is turned.

The right way to do it is fit 968 ClubSport springs, but they are dealer only and not cheap. You might get G-Max or some-such rubbish that fits but they will be poor quality and will lower the car too much would be my guess. The S2 and Turbo (later Turbo at least) use smaller diameter springs than Luxes so not all springs available fit.

You should certainly do everything at once: as it will need a full four wheel geometry setup, as stated. At the very least Id replace all four dampers with standard replacements (or better) along with all of the compliance bushes and the stut top mounts.

in reality three hours is more like it. Ive paid to have it done to two separate cars and neither has taken longer.

Who do you use for this Simon, is it EMC? I suppose because they do this a lot when building race cars they know all the best ways to save time - itwould certainly make the job a heck of a lot more resonable if it was 3 hours
