    This is what is says when it is 100% charged and I click on the battery icon. Does it mean that it is bypassing the battery and just running the machine on AC power, or is it still charging the battery? I just don't want the battery to get drained by leaving it plugged in.

    Leaving your Mac plugged in while it is fully charged is fine. Just unplug it and run it off of the battery once or twice a month to keep it healthy.

    Computer batteries have had chips inside them to prevent overcharging for years, this myth really needs to die.

    Plug it in as long as you want to, you're not damaging anything.

    Don't worry about it - The computer is designed to handle the battery charge level by itself :)

    It stops charging when the battery is full. It cannot overcharge. Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug any time you need to, regardless of the charged percentage, and you never need to completely drain your battery. Just make sure you don't run on AC power exclusively, as your battery needs to be used regularly to stay healthy. The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
