Srieck,
I think you should be perfectly fine. Later versions of the compact Macs (SE through Color Classic II) will have a bleed resistor attached inline with the anode cap and flyback transformer or just in series with those 2 parts. The whole purpose of the resistor is to quickly dissipate the remaining high voltage. And by quickly, I'm talking as soon as you flip the power switch to turn your Mac off. I believe all the dangerous levels will be gone within a minute. I know that seems like a very conservative value, but not once have I gotten zapped right away when working around the high voltage areas.
The parts with the highest possible potential for shock hazard is the CRT, anode cap/flyback transformer (anode cap all the way back to the metal cage), some of the larger capacitors and the power supply unit. I think the power supply unit has the greatest shock hazard of all since you are dealing with higher current (amperes) than the rest of the machine. You have the highest amps from the AC power coming in through the power cable (about 10-60 amps) and then it starts dropping as the voltage is changed and distributed out of the power supply to where it needs to go. The power supply will output your standard 12 and 5 volts DC and the analog board will raise some of that to a few hundred volts and up.
One thing to add: Scott Baret didn't mention not to forget to remove the plastic Reset and Programmer Interrupt Switch on the left hand side of your Mac before you pull the case apart. You're not the only one who has forgotten about that.
