made to the shield were to use rubber bands to hold it fast to the Arduino and to solder the pins going into the power, ground, and data in holes on the ring.

So the solder has to be removed with a solder sucker. Fortunately as long as you don't hit the NeoPixel too much with the iron the damage is fixable. The NeoPixels turn out to be pretty resilient. If your NeoPixel ring isn't lighting up as it should and you've soldered some connections, take a close look at your solder points for any bridging.
