Yep, they are called potentiometers, and can be purchased at Radio Shack for a few bucks...

No, you wire it in series to the circuit that is powering the LED's. Ultimately, all a potentiometer is is an adjustable resistor. It limits how much current can flow through the circuit that it is wired into.
