I'd hang onto those iridiums and check them later. I expect they'll be fine after a good clean.
You mentioned you had difficulty starting: damp on the HT leads or cap could easily have caused that and once the thing's built up a bit of soot on the insulator from misfires caused by that the problem continues.
Mine was pig too last week after 13 days sitting idle, a good thrash along the M4 and a chance to dry out thoroughly was all it needed. IIRC your commute isn't very long and is in town so the bike probably suffers more.
