This is a timeless argument , but I agree with Pickles , just drive normally and a little bit considerately, don't flog it for the first 5000 kms, avoid high sustained speeds/ loads, avoid over torque situation, ( low revs/ hard work).  I don't see how flogging the engine early on can bring a benefit to you, it's contrary to conventional  ideas. 
I don't see any need to change the oil if the engine has a centrifuge filter and good oil filtration. That idea has fallen out of favor. We do oil analysis after running in and the the oil is normally fine to go until the recommended oil change time. But people need to need careful about about ( "Changing oil before 20,000km is a waste of money") The oil might look clean that doesn't mean it has the same viscosity characteristic, or that the chemical additives are still the same.  The longevity of those characteristics is very much dependent on the oil. Eg in my volvo 265, ( they were tough on Lube oil), the XXXX oil I was using would go in thick, 5000 km s later you could hear the cam chains and valves, and notice the LO pressure was going down. ( change to Penrite HPR30)
 I have  attached, (maybe 

 ) a factory running in instruction for a marine CRD high performance diesel similar to  the modern landrover engine for your interest.
I would change the gearbox , transfer case, and diff oils after the first 5000-10000k,  Those gears will be lapping themselves in , and the debris will have not be filtered out, but held in suspension mostly.
