LP640 Diff and Gearbox oil

[Mr Prem]

HI All. I have had my car for over 8 years now and am feeling brave enough to carry out some maintenance myself. I have approached the main dealers and the costs are through the roof for something i think maybe a lot cheaper if I bought elsewhere. Can anyone recommend which oil i need for the front and rear diff, and the gearbox. Is it the same for both? Also which brake pads to go for? I have standard steel discs.

Thanks in advance.
