Default help me stay alive (mains)

listen:i've spent to much time reading and not enough building stuff (no time with anything 120V). i got this neat toroid and i need some suggestions on connecting it to this power cord i have. just solder and heatshrink? seems kind of weak.
also, quick dumb question: do i take this plastic wrapper stuff off the transformer? i'm pretty sure that's a no.

primaries are white and black.......build a test jig.....look on these forums before you go killing yourself and the cat....if you took "3" semesters of electronics then you should know how to hook a basic transformer....want more help from me then recite ohms Law

i know what everything is. its just the physical connecting of stuff.

remember this little triangle trick thing to help kids with the algebra of ohm's law?
Code:
 V
 -
I|R
i think i'm going to buy a plug instead of just soldering the cord to the transformer.
