I currently run a Centaur Ultra-Torque crankset mounted to BB cups on a standard English threaded shell. I'd like to try out a 52-36 FSA crankset that I've discovered for a decent deal, but I'm not completely clear whether I'd need to get an FSA bottom bracket or I could just use the existing Campy cups I have mounted to my frame.

The SL-K crankset is apparently a "386EVO", whatever that means (an FSA standard?). According to a chart at FSA's website it requires a 200-3201 BB-EVO8681/i bottom bracket.

However, couldn't I just use the correct size of cartridge bearing for the FSA bottom bracket and mount the bearings and the crankset to my Campy BB cups?

You need a new BB. Your Campy one won't work. No, you cannot reuse the cups.
