If a super conductor reaches 0 ohms of resistance and you put an arbitrary about of voltage, V, across the superconductor, what is the current? Does I =V/R still hold true?

No it does not. Ohm's law applies only to specific materials that have that constant relationship between current and voltage, and a superconductor is not such a material (neither is a semiconductor). One way to look at superconductors in the context of Ohm's law, is that because V=IR, so matter what the current is, the voltage drop across the superconductor is still zero. There is certainly not an "infinite current" because of dividing by zero resistance.
