I just got it tonight and it came with 70% charge so I just started using it without plugging it in. Should I have plugged it in and charged it to 100% first? Is it bad that I didn't?

It's at 56% right now, should I plug it in now?
 
No, you don't have to charge it before first use. I would recommend plugging it in, as soon as you finish OS X 10.7 Setup, and you're at the desktop.

I never plugged it in when I got it I just used it right from 70%, but is that going to cause my battery to suck now :(

No, it won't degrade battery quality. When you finish using the MacBook Pro tonight, or when the battery gets around 30 percent, then plug it in.

You don't have to plug it in at any certain percentage. Run on battery when you need to and plug it in when you can. Just make sure you don't run on AC power all the time, as the battery needs to be exercised to stay healthy. This should answer most, if not all, of your battery questions:

Thanks guys, -breathes out- I don't feel so much like an idiot for doing what I did anymore now :D

That's what I meant. Don't completely drain the battery. You don't need to do that until a month goes by.

You can drain the battery any time you need to, or not at all. You should cycle the battery at least once per month, but that doesn't have to be done all at once. Draining to 25% and recharging 4 times, or draining to 50% and recharging twice does the same thing.
 
I do plan on being stationary most of the time I'm using this MacBook (well, either at work or at home but I always intend on keeping it plugged in). Above it's mentioned that keeping it plugged in 24/7 seems to be a bad thing because it will harm the battery over a long period of time.

This might sound silly, but does that mean I should intentionally use my Macbook on only battery X amount of times a week per say?

Yes, exactly. You can simply unplug and run on battery a few hours, a few times a week. Then plug back in.
 
It's a notebook computer, it's meant to be used on battery, that's the point of having a portable computer. You aren't hurting your battery by using it, if anything you're keeping it healthy.

It's recommended once a month that you calibrate your battery. This is done by allowing the MacBook to discharge completely, leave sit for ~5 hours, and then charging back up.

I've calibrated mine monthly since I got it two years ago and still have 100% battery capacity.

Newer unibody Mac notebooks come pre-calibrated and do not require regular calibration.

Really? I never knew that...I was under the impression it was always good to calibrate the battery. I wonder if mine even needs calibrated.
