Never had an HSS guitar but IIRC the canonical solution is to use 250K pots and add a 250k resistor serial between the bucker and the volume pot. wrt/ tone caps, you'll probably want to wire it with both SC sharing a same cap and pot and the bridge using the second pot with a distinct cap (you should find the appropriate wiring diagram on
http://guitarnuts.com). If so get a 500K pot for the bridge tone.
My 2 cents (before someone way more knowledgeable chimes in...)
