You don't need to constantly discharge the battery, if you have access to your power adapter, use that, if you don't have access to it, use it on battery. And the batteries in Unibody MacBook Pros don't need calibration.

You don't need to intentionally use your battery until it runs out. You also don't need to unplug as soon as it's fully charged. Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug at any time, regardless of the charged percentage. Just make sure you don't run on AC power all the time, as your battery needs to be used regularly to stay healthy.

Also, read WHAT IS A CYCLE? in the following link.

That's because there's too much misinformation floating around about battery health. The inconvenient truth is that any measures you take to "preserve" your battery are ultimately pointless. You'll never be able to tell if your battery preservation efforts actually contribute to the life of your battery or not.

Use your computer how you want. Batteries are easily and cheaply replaceable if they end up not meeting Apple's generous specifications (1000 charges at 80% capacity at 3 years).
