Freelander 2 (LR2) 200,000 mile service & MOT

Taking my FL2 in to an independent Land Rover specialist next week for a nice, round, 200k service & MOT.
Haldex & Diff are on the to-do list.
The serpentine belt isn’t quite due, but I might have them do it.
Gearbox is still, as far as I know, on its original oil. It’s working fine, so do I leave it alone or change the oil on the principle ‘if it ain’t broke don’t fuck with it’?
Brake fluid was changed entirely earlier this year when I fitted new discs, pads, a calliper and a wheel bearing.
Coolant was also changed a couple of years ago when I replaced the thermostat.
Ditto power steering fluid when I replaced a corroded pipe last year.

Anything else out of the ordinary I should ask them to do or check?

Haldex fluid, filter and pump gause, yes.
Rear diff oil, yes.
PTU oil, yes.
Gearbox fluid, yes.
Front drive belt (alternator/PS/AC), yes.
Air filter, yes.
Fuel filler (genuine only), yes.

Brake fluid, no.
Coolant, no.
PS fluid, no.
