Is it safe to leave a light bulb partially unscrewed?
It would not be dangerous to leave a light bulb partially unscrewed, however, there is some possibility that it will fall out of the socket. I would advise that if you don't want the bulb to be on, and you don't have a light switch, unscrew the bulb completely and put it away until you need it.

What is on off switch?
Say it is a power circuit, a light bulb is bright from the battery, flowing through the wires and the light bulb. There is a switch controling the power that goes through, so if you switched the off switch off, the power will no longer be flowing through(the light bulb wouldn't be bright any longer).

Why won't a three way lamp switch work with a wall controlled outlet?
Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.
