You get a lot of quests and unfortunatly the journal leaves a lot to be desired in terms of what it logs. The painting thing was likely a quest from a certain someone in the Moonstone Mask (city core). As for going into house I sometimes do (and loot of course) but if theres hostlies attacking me and its not quest specific I dont go on the killing spree. But I'm neutral good so I'm not a complet maniac
