A leather cubby lid is a worthwhile upgrade in my opinion...remain to be convinced by the wood cubby lids as the only ones I've seen have been stick-on over the basic "leather look" plastic lids and they look rubbish. Suspect a real one is probably a touch OTT, whereas the leather definitely looks good. I personally feel the same about the handbrake lever and shifter knob...leather good, wood bordering on naff/OTT.
You have to be very careful about some of the P38 wood trim for sale on eBay. Sometimes the sellers "forget" to mention it's stick-on stuff and are very careful about the angle they photograph the bits from...and/or use a variety of euphemisms such as "walnut effect" etc. Almost got ripped off myself by a carefully photographed bit of trim in that way.
Having said that I reckon the stick on stuff can work well on the air vents, speedo unit, radio and HEVAC unit. It will never look good on the electric window switch panel, the front upper console and anything else that's not fairly flat and recessed (so you can't see the edges).
But some of the bits you get in a full stick-on kit are just plain wrong: binnacle around the speedo, interior door handles, trim around door lock pins etc.
Finally there's a Range Rover specialist breakers in Ramsgate that sub-contracts out to a guy who (presumably) airbrushes anything hard plastic with a very convincing wood effect. There's also someone else in the Midlands who similarly "veneers" shifter and handbrake handles and advertises on eBay from time to time. The work of both looks excellent in the eBay listings, but the prices fully reflect the time, skill and effort of the workmanship - I'm being realistically diplomatic...I'd never pay those prices myself, but they are clearly cheaper than a Land Rover dealer and I can see how they can be justified.
