When you bottle, the yeast wakes back up and eats the sugars in the carbonation drop. Instead of the CO2 that's produced bubbling out through an airlock, its trapped in there and absorbs into the beer which carbonates it. So, based on that, you'll need to store your bottles at room temperature. If its too cold, the yeast wont work, much like normal fermentation.
The other thing that's important when you bottle is making sure the beer has reached its FG. If not, and you bottle early, the yeast will continue fermenting the original sugars plus the carbonation drop and produce over carbonated beer and possibly 'bottle bombs'.
Make sure you have steady gravity readings over 3 days before bottling. According to IanH's spreadsheet you'll be aiming for around 1.017.
