Q.New Garden Location
We just moved an old oak woodpile. Most of the wood has decomposed, leaving about 5 inches of organic material with small pieces up to 6 inches. Should I rake out the larger pieces and cover the area with black plastic? Some wood had mold. Do I have to worry about that with a vegetable garden?

It will be a good place for a garden. The decomposing wood will help the plants. I would have the soil tested though, just in case. Sometimes the decomposition process can deplete the soil of nitrogen or make it acidic. As far as the larger chunks, as long as they are not interfering with your planting, you do not need to remove them.
