I recently did one of those on a cheap GFS Tele that I picked up during their "moving sale" a couple of months back and then modified extensively. Here are two excellent articles on the subject that I would recommend:

I "auditioned" several resistor/capacitor combos (all with the two components connected in parallel) and decided that the 680 picofarad cap & 150 Kohm resistor combo sounded best to my ear. "YMMV", as they say.
That's interesting. For a Strat or Tele with regular pickups, I would expect 1M pots to be excessively bright when wide open, but maybe the noiseless ones are a bit darker?? I haven't played those, so I wouldn't know.
