If you donate the items to a local charity, I believe that will please Woody mightily. He is not likely to stay attached because you would be honoring him by the donation of the items. That action should bring him Peace and solace and may actually help him complete his journey. Taking the items to the dump will create much ill will for you since Woody will feel as unloved and unwanted as his former posessions you unload there. Honor his memory and give him permission to fully cross over as you donate his belongings. Kindness and generosity are their own reward....you'll see.
