Ok, I called Radio Shack and they have 'potentiometers', which I hope
is the same thing. I just don't know which to pick because the one
they told me about is rated for 25 ohms...

Ok, thanks for that. I just want to make sure I buy the variable
resistor that will work through the range the first time. I do not
like taking things back if I don't have to...
Does anyone know a part number for Radio Shack that will work with
what I want?

If the batteries drive the LEDs directly, then there's no way that you can
burn them out by turning the pot all the way up -- in either case, the net
resistance in series with the LEDs is zero.
If there's a dropping resistor between the battery and the LEDs, the same is
true, if you leave the resistor in place.
