This site will help. I've pruned grapes for years, and found that over-pruning is better than under-pruning. A few years ago I whacked the heck out of some muskies we had growing along the fence row and we had more muscadine grapes than we could handle. they were growing wild, had never been tended, and a good cut back really helped them recover.
Sorry I can't help with blueberries. They require acid soil, and we have alkaline soil and can't grow them except in containers.
