I know how to remove the micro switch, I'm just nervous about those wires...(http://www.x-arcade.com/service/images/innards/msconnector.JPG)

Grasp the quick disconnect terminal (QD) between your thumb and forefinger, like you or whoever is doing in your picture, and pull it straight off the microswitch's tab. If they are on particularly tight, you may have to rock the QD back and forth some as you are pulling to get it off.
Maybe I'm not understanding the question...

You won't get shocked if that is what you are worried about. Even if you did, it would barely tickle. ;D
As to the metal tabs on the microswitches, they are pretty durable. I've never even come close to breaking a tab on a microswitch - leafswitches are a different matter...

I wouldn't be afraid of hurting anything. The micro switches are rather robust. Just don't use any tools other than you fingers. The voltage running through the wires is around 5 volts and a few milliamperes. Less than a 9 volt battery. The micro switches are rated as several times that amount. If you really want to be safe just unplug the power source from the wall outlet.
If you don't want to take the chance of mis-wiring the switches then label the wires prior to or just after removing one.

Top (bottom) connection is for your ground wire. The connections on the side either are for always on (until you push the button) or always off (until you push the button). For 99% of the applications you will use them for, you want to use the connection closes to the ground as that is the always OFF connection...until you push the button which then makes contact momentarily...

Of course, good practice is to remove power from the circuit before working on it, to prevent a previous mistake from frying your nutsack.

There is nothing about touching the ground signal that can hurt you. It is about as harmful as sticking the key in the ignition of your car (which is grounded)

That's why I said a previous mistake can hurt you. Having wired something else incorrectly can lead to an unknown state. Odds are low but why risk it? Just unplug the damn thing. The guy is obviously still learning so keep him safe.

I always use a pair of pliers to get a better grip but there's nothing fancy to it - I just yank them off...
