The past month the order of spare parts has come in and I began changing older parts in advance of the trip. The list of parts that I've ordered and will be carrying with me are as follows: Front brake pads, Rear brake pads (2 sets), Grooved front & rear brake disc's, Track rod ends 2 of each RH & LH threads, One shot swivel grease (2), Pinion seal (2), Wheel bearing kit (2 sets), 300Tdi motor service kit (basically filters), 300Tdi Radiator coolant hose, 300Tdi Fuel lift pump, Series Universal joints (4), Hub gasket (4), Hub driveshaft cap (2), Series wiper arm kit, 300Tdi serpentine belt (long version 1595mm), Air Lift - Suspension Aid, Defender V8 rear drive shafts both RH & LH sides, Clutch master cylinder, Fuel tank sender gasket (2).  Below is an image of just a few of the parts.

Knowing my hybrid I think that for me that I've ordered the necessary reserve parts for any road trip. It's an unknown to guess what your going to need but with the parts that I will have with me and a full tool kit, I should be able tackle any issues on the road. The brakes are already changed over to the crossed drilled/grooved disc's which has improved braking. With the weight that I expect from all the kit during this trip, braking was a priority plus I will be carrying extra brake pads if they need changing along the way.

Even though I have Defender 90 HD rear springs I ordered the Air- Lift 1000 helper air bags to compensate for the extra load. The 90 HD springs are dual rated, which means that they compress a lot before they get into the HD range. By using these air bags the hybrid will keep a better posture on the road and will improve handling. These will be installed the week before my trip as I have an offroad event just before that.
