In my opinion, it is bad advice to replace anything (except your pickups). I would agree that pickups make a big difference in the sound of your guitar. Pots, capacitors, jacks, wiring and switches only need replacing if broken or noisy. I have the cheapest components in my guitars, they sound great and they're not noisy. The capacitor only works as a low-pass filter when the tone pot is engaged. How often do you actually use your pots? I know I only use my volume pot to shut my guitar up.
case study: My brother bought a Tokai LS160 with all those 'wonderful' goodies such as switchcraft jacks, cts pots and sprague orange drop capasitors and in all honesty it makes no difference. We both prefer my washburn raven with no-name electronics and my 2003 squier with garage wound pickups.
