Tolovemoon's Photo A Day and maybe a little more :)

I have been wanting to do this for quite some time..
I started visiting Piano World Forums and it was there that I read about what I need to do this.
Still not exactly sure about connecting to the pc.
I dont want to mess up my sound card, why didnt they color code this?
Others are still asking about this too, so I am including some pictures of the cords I bought from Radioshack..


These should be connected to the mic line in right?


And here is the midi side, but I dont have anything for this side, dont think I need it..?
