Remarks

DeleteLayer will automatically recalculate the Map's extent after the successful deletion of a layer.
Tips:
If a layer is selected in the TOC window (IMxDocument::SelectedLayer), you can pass this to DeleteLayer.
When deleting a layer that references a feature class, like a FeatureLayer, executing IDataLayer2::Disconnect will ensure that references to the feature class are cleared.
