The Z system is how we organized the different sample prints:
Z1 is printed with the overhead and close mic
Z3 is printed with just close mic
Z4 is just the room mic
so you combine the Z1/Z3 with Z4 to get ambient drums.
If you want to program the drums, I suggest getting Kontakt.
If you want to replaced already recorded drums, be it live or programmed, I suggest drumagog, but you COULD use the raw wavs and get them in the project manually or by "tab to transient" method.
