OK - for better or for worse I am now Malev Gold

I fell out of the BA arena some time ago, so the status match worked well, getting me back into T5 lounges.
But keeping status looks like being hard work as I'm not really familiar OneWorld workings. But I sense with my travel patterns the sectors (30) might be easier to achieve than the miles (80K).
Can anyone suggest a cost-efficient way to pack multiple sectors into a trip? The US and SE Asia are my non-European travel areas.
