120000 Service

Hi Guys,

This is my first service that I need to do on my 325i steptronic (E46) at 120000kms,

Besides, oil, oil filter, air filter, plugs, is there anything else that needs to be done and if so, where is the best place to get spares (Sandton/Woodmead area)?

What plugs is best for this car?
I service my Conquest myself but it is my first BMW service so any advise would be welcomed.

Thanks
