I know i have to be careful with the monitor, but what about wires from the power supply, or wires from the monitor? Can I get zapped by these? Thanks alot! :)

I thought this would be easy, any? Please, i need to get started. Thanks alot!

Part of the answer depends on the exact monitor/chassis/etc... that you have.
You would probably be best off to go to Bob Robert's Website (http://www.thetrealbobroberts), and read about how to properly discharge a monitor for removal.
There is good information there about discharging a monitor, and also about avoiding getting bitten by a G07 chassis.
There is one capacitor on the G07 chassis that will stay charged when you discharge the monitor anode, if one of the fuses is blown.
You have to discharge that capacitor as well, before removing the monitor chassis, if you don't want to drop it suddenly when it bites you.
The one other thing to be concerned about is proper handling of the picture tube itself.
You don't want to crack it, and have it implode on you.
The power supplies, and wiring associated with them (runs to the PCB board, controls, isolation transformers, etc...) themselves are relatively safe, provided they are unplugged from the wall.

One thing that I always do, not being a cab wiring expert myself, is take pics of all the wiring connections before I take everything apart. Of course this is only relevant if you are planning on putting everything back together, if you are just gutting then you don't need to bother. This approach has been invaluable to me in the past.

Ok, you only discharge monitors if you have to take the Anode cap off, and that is the ONLY reason. You don't discharge them simply to remove the monitor.
Sounds like this guy is just gutting a cabinet, probably a dead one.
You should be careful that you don't break anything, thats it.

I'm in the "better safe, than sorry" camp on this one.
While I will admit that I don't discharge them when swapping/moving/rotating, I wouldn't recommend that to someone else.
I will discharge them if they are going to sit uncased though.
I don't want a curious kid/cat/dog/etc.... deciding to see what's under the big rubber suction cup.
I was doing some rewiring on my Radical Radial the other night, and didn't realize the cat was in the garage until she stuck her head into the cab from the back side, right near the neckboard.
I'm guessing fried-cat-smell is even harder to get out of a cabinet than smoke-smell.

It is more dangerous to go around randomly discharging monitors that aren't being serviced than it is not to do so.
Also, in all reality the sucker isn't going to be holding a charge if it hasn't been on for a few days. Most of the arcade guys I know will rip the anode cap off a monitor that has been sitting without even a second thought about it.
The REAL issue with monitors out of the cabinet isn't the anode cap, it is accidently bumping the neckboard and thus breaking the neck.
-
In some of the newer Midway games manuals (crusin exotica, the grid, etc.)
they say before you remove the monitor, discharge the monitor first.
-
THEY say that for exactly the same reason I said that.
It's OK to remove charged monitors yourself (if you know what you're doing); but you can't control how others do it, so you don't want to recommend it.
