I've got 2 paralleled 303's, and I'm looking for views on the best setting for bias after adding extra diodes at MR105 and 106. Any ideas?

Higher current capability doesn't have anything to do with the correct bias setting. You should still aim for what it says in the Quad service manual. However in practice it is easier to do this by measuring thevoltage across pins 4 and 6 and aiming for about 7.5mV.
