Sorry to tell you but finding coke deposits on the oil pickup like you did isn't a good sign.
Not what you want to hear but it's pointless fitting a new turbo unless you try to clean the engine the best you can, you're going to have to remove a lot of parts to clean them.
You need to perform everything on the list below, you could clean rather then replace some of the parts.
• Turbocharger oil feed pipe & banjo bolts must be changed
• Oil pump should be removed and checked
• Sump must be removed and cleaned.
• Check that engine has latest specification sump and dipstick.
• Oil strainer (pick up) must be removed and replaced due to residual carbon/sludge build up
• Oil cooler and filter assembly should be removed and cleaned
• Charge air cooler to be removed, cleaned thoroughly and any oil inside drained off
• Inlet and outlet hoses to be checked for damage and cleaned
• Exhaust system to be checked for contamination/blockage (Catalyst, DPF etc.)
• Vehicles with DPF: carry out static regeneration according to manufacturer's guidelines
• Brake vacuum pump to be removed and checked for debris/carbon - clean as necessary
• New oil filter and oil to be fitted
• Fuel injector gaskets to be checked as not burnt or compromised - replace as necessary
• Oil drain pipe checked for blockage/restrictions and cleaned as necessary
• Oil flow must be checked:-
• Fit turbocharger to engine leaving oil return pipe off
• Install a longer oil return line and feed into suitable container
• Start engine and idle for 60 seconds, then switch off engine
• Measure volume of oil in container
• 60 seconds of idle should produce at least 0.3 Litres of oil
• Repeat test two or three times to confirm oil flow is correct
• During this test. do not allow engine to run below minimum oil level!!
• Vehicle should be driven 20 to 30 miles then the oil/filter and banjo bolt/filter must be changed
• Advise oil/filter and banjo bolt/filter are changed at 3000 mile intervals

These things happen and I'm a stickler for doing a job properly, so thanks for sharing that list.
