I don't have experience with the single piston brakes on the FC, but I know what single piston vs. multi-piston brakes look like.
Single piston brakes look like this:

If you remove the wheel (or if you can see through your rim) you'll notice from the side profile that the pad is visible. In other words there is no covering from the outside of the brake to the pad. The four piston caliper brakes have metal surrounding the pads, except for the very bottom. You will also notice that that there are two circles about the size of quarters on the outside of the four piston caliper metal casting.

As for the slotted/drilled rotors I would STRONGLY recommend that you guys use some common sense and spend your money more wisely on some other area of the car regardless if it is cosmetic or performance related. Even if the costs are similar to vented rotors the long term costs (ie. reduced lifespan) will probably end up costing substantially more.

There will also be the word "Mazda" in raised letters on the outside (wheel side) of the caliper if it is the 4 piston unit.
