If you are sticking with the 312MM Fronts i would personally go for OEM/Plain Discs either Genuine or Brembo, Ferodo DS2500 Pads and some decent Brake Fluid such as ATE TYP 200 or the likes. If you want you could also replace the Brake Hoses for some Braided Items also.
I am not a fan of anything that is Drilled or Grooved, The C and J Hook Discs you can get are better but for normal road use with the odd spirited drive I would not bother.
Sorry if this sounds ignorant but what difference will new brake fluid and braided hoses make ?

Repeated applications from high speeds create a lot of heat in the Brake Disc/Brake Pad and this transfers into the Brake Fluid which causes it to boil creating a spongy pedal/Brake Fade. Decent Brake Fluid with a higher boiling temperature will take more abuse/repeated applications, Braided hoses firm the feel of the brake pedal as there is less flex/expansion in a braided hose rather than the standard rubber items and do not deteriorate like rubber hoses too.
Some uprated Brake pads may even not perform as well when cold as your standard VW items, However they will be able to operate at a much higher temperature than the VW pads and will still be efficient due to the fricition materials used. This Higher temperature that the uprated pads can operate upto is only as good as the Fluid that is in use!
It depends what type of driving you are going to be doing but if you are putting Performance Brake Discs and Pads on the car then you ideally want a decent Brake Fluid and Braided Hoses too to make the most of your set up.
