Since its a single pickup, you dont really need a switch, unless you want to do some kind of coil split/coil tap kind of business. Personally, what I think would be cool is a tone control like this guy did that allows for single coil tones without an additional switch. Very cool.
GFS does good bang-for-your-buck pickups, and IIRC makes "plug and play" sets that require little to no soldering.
And are you talking about gold knobs like these ones (barrel), or these ones (top hat)
