I have an outdoor hose copper pipe that I cut and I'm assembling a gatorbite coupling on the piece I cut going to the house and the new pipe with the hose fitting. My question is the coupling came with a white plastic piece that fits into the pipe. There is also one in the gatorbite coupling. Do I use the two plastic piece?

I am sure I can help you as soon as you better explain what you mean by "outdoor hose copper pipe " Is it rigid copper pipe or a hose. The white plastic piece is a bushing used to firm up tubing that is soft, not needed with rigid copper or PVC. http://www.ehow.com/how_8501659_install-gatorbite-coupling.html
