I've only got 2 or 3k to do before the dreaded 90k service

So, if I'm stumping up, I may as well get exactly what I want done for all that cash

Oils: Engine/Gearbox etc. which brand? Syntrax for the gbox?

Plugs: Best brand? What's the best gap? I've heard anything from 1.1mm to 0.7mm...

Is it likely that leads etc would need replacing? - I do have a minor hesitation, particularly apparent between 3 and 4k

Brake fluid?

Anything else I should look for/insist on?
