I am not a SQL tuning guru, but it looks like this is an ideal example where Hash joins would be of immense help. You could set a largish value for HASH_AREA_SIZE (defaults to twice SORT_AREA_SIZE) to reduce visits to TEMP to write out hash tables... It would be nice if you could post the explain/costs for all three methods at the end of your tests.
