The important differences between the perspective view and a camera are that changes to the Perspective view aren’t added to the undo stack and aren’t keyframed (and its state isn’t saved with the scene). That makes it useful for setting up, since it doesn’t jump around if you change frames or undo an action, but useless as a final rencer view. So yes, add a camera for rendering the scene but don’t use it for setting up.
If you want the default head lampso you can see what you are doing as you set your sceen up switch off preview lights, in the Window menu.
