Girlfriend got me a stove that came with this bottle... Where do I fill it? How do I use it once filled to refill the smaller canister? Am I way off base?
Buy a bottle of liquid fuel and pour it in... Honestly I suggest you read the manual and probably watch a few videos of your new stove being used just in case you do something silly.
You should really just use "White" gas, preferably the MSR brand as other brands are dirtier and will clog up your stove over time. (i've only found it at REI in my area)
Coleman camp fuel is good too.
Seconding this, if you don't know how to use a whisperlite, you'll probably end up setting something on fire.
in a nutshell
attach hose, pump, and bottle to stove.
pump 10 times or so.
open valve slightly and watch for liquid fuel to fill your primer cup (at the bottom of the coil is a cupped piece of metal)
when its almost to the top, turn off the gas.
light the gas, careful of the flash
let it burn out completely (this will prime your fuel pipes via black magic, i dunno how it works)
pump 15-20 more times
open valve and you should hear the hsssss, (if liquid fuel comes into the primer cup instead, repeat the above process)
Light stove top quickly, adjust gas until you have a steady flame from the element
>Where do I fill it?
Camping department. Coleman fuel. Buy it.
>How do I use it once filled to refill the smaller canister?
Fill the 22oz. bottle to the fill line. Turn the valve of the pump off and screw it into the bottle so it seals tightly. Pump about 15 times. Attach the hose to the pump, and flip the bail over so it locks. Attach the other end to the stove. Set up your windscreen and heat protector. Make sure the G jet is installed, and bleed some fuel through the line so it soaks the priming cup, and shut it off. Ignite the fuel and wait for the flame to sufficiently heat the generator tube. It will start hissing and fuel will start to ignite from the jet. Wait till it's almost out and open the fuel valve on the pump. Adjust if necessary. Don't overpressurize the canister.

Turn it off, let it cool, and do it again. Don't go camping until you can do it with your eyes closed. Practice in the wind.
