Oil leaking from here drips down the center housing and gets on the turbo exhaust manifold, which then burns and smokes...

Interesting, I've never had a problem getting that stock flange joint to seal up properly, never had a leak there. Perhaps your flange or turbo mating surface was warped or misaligned somehow?
I just use the factory paper/fiber gasket, with a very thin & even skin coat of blue Hylomar on both sides of the gasket & torque bolts to FSM spec. My current BNR turbo setup needed an oil pressure restrictor to prevent smoking, so I fabricated an 0.096" thick AL restrictor plate and sandwiched it between the oil feed pipe flange & turbo with gaskets on all mating surfaces. Needed slightly longer bolts, but it still doesn't leak, which shocked the hell out of me.
