Yes, you'd use the 1000mA buckpuck with a white LED. An important bit to remember: buckpucks need 5v minimum to turn on. If you go that route, you'll likely want a 7.4v li-ion pack.
I usually wire my switch LEDs in a parallel circuit to other components. You don't want it in series with your main LED. If you do that, you'll either end up with a really dim blade, or a burnt out switch LED.
