Probably best to stick the FTO up on a ramp and examine the condition of existing bushes - if the front and rear Anti Roll bar bushes have not been done previously its almost certain they could do with being replaced (pref Poly Bushes). Similar story for front and rear droplinks - shortened preferably as you'll be lowering your car (Camskill sell these).
Theres quite a list I could go into - I'd personally change the dampers to KYB's as well - they are very reasonable and a nice upgrade to tired old FTO OE spec -

May be a good idea to do a search on suspension and then make up your own mind - I think its a very good area of the FTO to mod - I previously changed front and rear ARB bushes (Poly) , F & R droplinks, KYB Dampers and Apex springs, All remaining bushes changed including increased castor poly bushes on the front arms and also fitted a front and rear strut brace. Spent a few quid (less than a grand though) but it felt like a different car.
Also as you're changing the Discs now would be a good time to consider some braided brake hoses.
