Oil on the outside is caused by the valve covers not tightened down enough I get that all the time. Its more prevelent towards the back of the engine than the front. Scince you have the throttle body off when changing the plugs its a good idea to check the valve covers. If the plugs are oil fouled on the inside where they fire than the rings could be weak or valve seals could be leaking. Beefing up the ignition to a multiple spark type might help burn the oil better but it won't cure an ailing engine.
The problem with the Toyota head design is the spark plugs are right in the middle and anything that gets trapped up there be it water oil or sand it stays there.
