So I bought a module for supplying my ESP8266 with 3.3V it requires, since I currently have it running off of a 3.3V pin of an Arduino, this is the module I bought:

How do I wire it up?

So I have a power plug that outputs 5VDC/1A from the wall, so I would need to take apart whatever wire comes out of the wall-wart (which is just one of those phone charging cubes) and split the wires up in order to feed this module?  It seems kinda clunky way of doing it.  Any other ideas of how to do this?

I guess you missed the spec that your devices needs a minimum of 5.5 volts. When you get something with that or more volts, then you can worry about the wires and getting the + wire and the - wire connected to the correct input connections.

That's OK, I've got a 9vdc as well as a 12vdc.

The terminal blocks are clearly labelled in+, in-, out+, out-.  Its probably (but not certain) that
the two negative terminals are common - you can check this with a multimeter.
