Wheel going out of true? How do I tell?
I am 214 lbs =D I have a Giant Defy Advanced 3 bike with Mavic CXP 22 wheels.
Recently, when adjusting my rear brake, I noticed that when the brakes were adjusted to be pretty close to the rim, that when I spin the wheel it will "bobble" over and touch the brake pad in a certain spot, ever so slightly. Does this mean that my when is going out of true, and I need to have the spokes looked at or adjusted?

Yes. You can do it yourself if you get a spoke wrench which you can get for <$10 at LBS. There are a TON of tutorials about truing on the internet. Read up on it and see what you think. It's really super easy if you have a little patience.

Tighten 2 or 3 spokes on the opposite side to the touched brake pad, and loosen 2 or 3 by the touched pad. only turn the nipple 1/4 turn before checking again. You will get a great sense of achievement when you make the wheel spin with no wobbles. Pluck the spokes so they all give the same note on each side, and tighten any that give a noticably lower pitch - this has to be done with no reflector on the spokes..

Don't just start turning nipples! YOu need to take note of where the rim is and which direction it is out. If you just start turning blind, you may pull the entire wheel to one side depending on how far out the wheel is. Then the tire may rub on one of the chainstays if you do it incorrectly. I use a dishing tool to check it. Some just use a stand but I prefe the tool. But you can pretty much tell when you put the wheel in the frame.
Before I turn anything, I mark the spokes with a black dot (Sharpie Marker). This way I can tell if the spoke turns with the nipple, which it shouldn't. If it does, you are likely to bind the spokes and get a false sense of being straight along with a chance of popping a spoke.

Before you start, it is best to read one of the instruction sites. I say this so you can decide for yourself who is correct when I say that I would loosen the spokes first, then tighten the opposite side. This allows the spokes to be loosened and given slack so that they may be pulled correctly into place.
I myself wouldn't "tighten" spokes first.
