You don't really want to lift weights daily, you want a recovery day between each workout (unless you're working different muscles each day, but that's inefficient). And you'll get a good core workout with just heavy squats and deadlifts. You contract the abdominal muscles hard (Valsalva maneuver) to help stabilize the back and keep it in extension.
Yup - different muscle groups on different days, and you don't need to kill yourself doing it. Work for tone, not purely muscle mass.
You can do that other stuff too, but it isn't really necessary.
