On this transforner the green wire is actually one of the AC inputs (wired as neutral here). The green/yellow is the ground/shield.
There is a reason why im asking, because I don't no anything about this stuff but im smart enough to ask because i know i can die.
It came soldered like that.
So, I put a screw through the chassis connected to a wire that will be soldered to the yellow/green wire at the base of the outlet? And then I wrap all those with electrical tape and dont ever touch those right?

You should be OK to test it like that. Just make sure the power cord is plugged into that IEC socket BEFORE you plug it into the wall. Don't grab the IEC socket to plug/unplug the power cord while it's plugged into the wall.
Watch the end of that red wire though, there will be mains AC voltage on the end of it.

I have some Edcor transformers MXL8CS at 1:8 that I use for I/V, and the big XSM at 1:4 that they sell for $13 which are an amazing value if you need something that big. I bought those to use for a cheap trial with 1794a someday. I haven't tried any of Edcors at 1:1. Since you only need two for a dac, I would go with the Jensen JT-11-EMCF for $50 to get into an 80% nickel core. They sound excellent. If it was for six channels in a crossover I might be tempted to play with something cheaper but for two channels it is worth it to spring for something really nice.

The XS440 looks like one worth trying. Nice frequency response, but they don't give any mention of the input/output impedance.

this thread deals with Vout dacs
I don't know why anyone want to use out transformer (the quality tx Is expensive)
here Is very interesting thread http://www.diyaudio.com/forums/digital-source/42441-out-stage-sony-cd-players-5.html how to build discrete output stage using jfets
there Is a schematic which allows to get rid of coupling cap http://web.archive.org/web/20070219232819/http://perez.r.free.fr/XB_out_fet_dc_0v.JPG
It Is for sony xb940 but I think It can be used with Vout dacs like wm8740, cs4397/8

The Impedance will be a reflection of whatever it is hooked up to, in parallel with its open circuit impedance which is always in the many thousands of ohms, 150k or so. They are like mirrors.
The listed rating, when there is one, is the load that it can drive and still meet specs. If the load is higher numerically, the performance will be higher also.
.01% distortion @1Khz is not very good for a trafo, at lower hz it will be several magnitudes higher.
There are several very good reasons to use trafos. The top one is, they sound great.
They eliminate the DC offset voltage from the dac chip outputs, eliminating the need for coupling caps.
They supply a certain amount of ultrasonic filtering.
They supply you with a differentially balanced output which is great if your other components are balanced, as mine are.
Borrow a couple from someone and try it before you knock it.
