Will using a GFCI breaker to power a circuit that already has GFCI receptacles in it provide any greater protection? Or will it make the circuit too sensitive, thus allowing the breaker to trip more quickly than designed for?

The only added protection would be if a ground fault were to develop in the cable between the breaker and the GFI outlet. Possible, but not likely. Also, anything that trips the receptacle will trip the breaker, so you'll have 2 things to reset.

If you want more protection, consider an Arc Fault Circuit Interupter.

and see the posting "Arc Resistant Breakers " on this board.
