The Power supply you have will work just fine. Here's photo (pardon my Paint skills) of how you should hook it all up. All it really comes down to is "doubling up" on the negative connections from each string of leds to the CAT4101"s and the PWM connections. Your setup only requires a 3 channel control code if the board is wired up like I've shown, since two CAT4101's will be connected to the same PWM signal. You can use the same six channel code that I posted earlier. You'll just have to adjust the variables for the 3 pwm pins that you're using, instead of all 6.
