You can probably shorten quite a few of these phrases very easily.

i.e: Change:

Refunds will not be provided, if you feel you are capable enough to replace the LCD/digitizer, then great, but if you feel you are not capable enough and you end up damaging anything then Refunds will not be provided. Once the product is shipped, no refunds will be provided and it will be the buyers responsibility.

To:

Refunds will not be provided if damage is caused while the buyer is replacing the LCD/digitizer. Refunds will not be provided once shipped.

or:

While I was replacing the screen, nothing was damaged at all. So I know for a fact that everything including the camera, sound, home/volume/power buttons, etc. works. Because a bit of the top portion of the LCD/digitizer was visible, I was able to see if everything worked properly (even though the bottom of the screen was not visible, it was still touch sensitive) so I was able to see if the camera, sound, volume, etc. worked. After that, I went on my computer and reset the iPod to selling ready settings (erased all music, photos, etc. it now resembles an iPod that wasn't used).

To:

Camera, sound, home/volume/power buttons are functional. iPod has been reset to selling ready settings.

Just give the bare minimium in the posting & tell interested buyers that you are willing to discuss things in greater detail.
