If you want to see a show while you're in town, try and grab some tickets at Teatro Sociale in Como City Centre. If you enjoy the show and want to see another, Cinema Theatre Chiasso isn't far.
If museums are on your list of things to see in Como, then you might want to head to Volta Temple. If you want to see more of the museums in Como, Civic Art Gallery and History Museum (Museo Storico G. Garibaldi) aren't far.
