    If I need to charge my MacBook Pro, but don't have enough time for it to fully charge to 100% (at 32% currently). Is it bad to plug it in and let it charge to 75%, or whatever I have time for? Does not charging it completely damage the battery?

    No, it's not bad at all. 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.

    Li-on batteries such as the one in modern electronics prefer to be subject to "shallow" charges "higher up" in the percentages... For example, 100-70% as opposed to 100-5%.
