I searched through the forums and found a lot of topics and information on batteries on the MacBook. I did perform a calibration and afterwards, the Amperage is showing 0. Is this right?

Yes the Amperage is shown when charging or not charging. 0 amps means your not in a charge cycle and your running on the power supply. If you check it when it is charging it will show a reading above 0. If your running on battery only it will show a negative number showing power is being discharged.

Here are some tips on battery care.

It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate or for a few minutes to use in another room. You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.

It is best not to use your battery unless you need to. Some people have hurt their batteries by charging then discharging every time they use the MacBook. This will age a battery very fast and cause you to buy a battery sooner than you should have too. Don't discharge the battery just because you used it. Li-Ion batteries prefer small charges over big ones. Use it and then plug it in as soon as you can. The only time my Battery is ever fully discharged is when I'm doing a calibration.
