My heated bed keeps shutting off, so for the time being, I would like to simply disable it to test out some printing and calibrations. How does one go about disabling the heated bed without unplugging wires?

AFAIK the only way to disable it is to recompile the firmware with HOT_BED set to -1 (see Platform.h).

So long as you don't have a "wait for heated bed to reach temperature" command in your gcode, why does it matter? The gcode placed at the start of the file by slic3r can be modified (on the printer tab, I think) - I use the settings from RepRapPro and I don't think they include a "wait for bed to reach temperature"

Simply comment out the bed temperature and wait for bed temperature commands in the G code file and the bed heater will not switch on. (G-code files can be edited in any text editor, e.g. Notepad).
