If you are loosing coolant then it's likely a head gasket leak, if you are loosing gearbox oil then it's more likely to be the clutch side crank seal. That said, water pump seals should be changed on a regular basis.

Also, I think your crank case oil would be white if the WP seals were bad. As Rich said, changing them is always a good idea. To me it sounds like you have a head gasket problem.
