This is definitely not an emergency... but I have a biocube 32 and they are super simple. You don't really need an ATO unless you are removing the top, they lose very little water to evaporation. As far as heaters, a decent quality 150w water heater should work fine.
The lighting schedule on these things is tricky (i replaced mine with the steve's LEDs so memory may not be perfect) but basically you want to set the blue channel to be on the longest (i think i did about 12 hours for my blue channel), your sparkle whites for about 10, and your bright whites for about 8. So like 10am-10pm the blues are on, 11am-9pm for the sparkles and like noon to 8pm for your pure (bright) whites. I can't remember which channel is which because it's been a while since I used the stock lighting.
