Hi Neil,

all bearings are lubricated by the manufacturer, so for the initial assembly and first prints, you don't have to lubricate them.

However, for the maintenance, it is a good idea to use lubrication.

My general Reprap Lubrication Guidelines:

Apply lube by wiping lightly with a clean paper towel dust-free cloth, and spread evenly by running the axis to its extents.

Rapid moving linear bearings or bronze bushings on rods: Low viscosity oil (Machine oil http://amzn.to/2kPPcrl)

Z axis LeadScrew(s): grease or even high viscosity oil (if you've already chosen one then stick with that)

Plastic Extruder Gears: Grease (http://amzn.to/2kPEj8J) (white lithium, PTFE, or silicone based are all great stuff)

IGUS Bearings: Dry lubricant (http://amzn.to/2jTiUYl) or none at all.

Don't use traditional WD-40 for lubrication. (Though you can use it to clean metal parts.)
