On the zetec at 60,000 I would replace all belts and the water pump. (OEM pumo has the plastic impelelr and will not last) By the way, www.lonestarparts.com sells genuine Ford parts at wholesale, my water pump cost $65 from them.

Why wires, plugs yes but wires usually go 100,000.

You have the rest covered, maybe look at hoses if they look bad but with a 99 should be okay
