if it's unplugged, can i safely handle all of the parts without worrying about getting shocked?

NO. You have to discharge any large filter capacitor by shorting the terminals. Capacitors are like batteries in a sense, they store electricity. Sometimes they put a discharge resistor to bleed off the charge... If you don't know what a capacitor is then why are you getting in to it..If you do then good luck....

I do not recommend opening CRT's or any monitor, they have allot of dangerous components, some CRT's are known to have capacitors that still hold a charge along with the tubes have very high voltage, and could be lethal. I know alot of experienced tech guys and that's one of only things that scare them, opening CRT's. If you do go along with this I advise to unplug it and leave unplugged for at least 2-4weeks. Be safe!

The CRT itself is another large capacitor that is charged to a really high voltage. The best way to discharge it is to connect a jumper to an axial lead resistor. Ground the jumper. Hold the grounded end of the resistor with a pair of needle nose pliers with insulated handles. Poke the other end of the resistor under that rubber boot where the high voltage connects to the tube. Then gently disconnect the high voltage lead and poke around in the hole some more with that resistor.

NO! The capacitors on the flyback (high-voltage) transformer will still be charged. Flip the circuit board over, handling it by the edges, so that the side with all the pins sticking out is up. Then, drop a sheet of aluminum foil on this side, and pour sand on it until the sand is about 2cm thick -- this will short all the leads together and safely discharge capacitors.

Shocks are not the only problem. You also have to worry about scratching or smacking any delicate glass parts to keep the glass envelope from imploding and turning into shrapnel while your hands and face are near it.

NO there can be lethal voltages in there. If you don't know what you are doing stay the heck away from the inside of a monitor.
