What do the temperatures on the different guages of wire mean?

The temperature is the value when the wire reacts (changes shape / moves / transitions from martensite to austenite). For example the 80C wire you need almost boiling water to have it react, while the 40C wire will react with less heat.

If I order more than 1, in quantity do they cut the wire into 1ft segments or is all one continuous piece?

Yes, you will receive a continuous piece.
