Hi Nyall,
I haven't had need to tweak the tile size so I can't offer any advice there.However I have had success adding authenticated WMS layers to 1.8 with this code:
if len(self.user) > 0 :	connectionString = "username=" + self.user + ",password=" + self.password + ",url=" + self.urlelse:	connectionString = self.url
crs = self.iface.mapCanvas().mapRenderer().destinationCrs().authid()
layer = QgsRasterLayer(0, connectionString, self.title, "wms",[self.layername], ["default"], "image/png", crs)
if layer.isValid():	QgsMapLayerRegistry.instance().addMapLayer(layer)
This code manually adds the username, and password parameters to the connection string, you may want to try something similar with your URI.
