Mark,
Biasing is done with the power on and the tubes warmed up. Make sure your meter is a good one and that the decimal point is in the right place for DC mili-volts. If you use a metal screwdriver (Not recommended for beginners) make sure it's tapped up pretty good (scotch 33 electricians tape). The potential inside an amplifier is well over 300volts and yes you can light up your world if your not careful.
If you feel at all nervous or uncomfortable take it to a hi-fi or electronic store. Usually a decent Electrician would be able to perform this task in a pinch. (Audiophile electrician preferably) good luck!
