OCUK don't seem to have everything you'll need so it becomes quite difficult to provide links for everything (would be against the rules of the forum).
Rad - Black Ice Nemesis GTS 360
Fans x 3 - Would recommend digging online for the Scythe GT1850's, even if you need to order them from America they're worth the wait. Sure there are similar alternatives but the GT's are silent even at full speed (no annoying tone) and push much more air than others. The static pressure rating is excellent also.
Tube pump/res combo - The EK one you linked or similar
Tubing (you'll need 2m to be on the safe side) -

Fittings (you'll need 6 if you're going for a pump/res combo) -

If you want to use a coloured fluid I would go with the coloured EK premix 1L, or a Mayhems Pastel 1L premix.
That should be pretty much you good to go.
