I like fresh ginger for chicken or fish dishes. You can either mince it or grate it (over the pot you are cooking in becaues grating pretty much juices it). Try Ginger, garlic, green onion, white wine, and some soy! It's yummy
You can also use the ground ginger for baking- ginger snaps and the like....
I also put a *smidge* of it in place of fresh ginger if I don't have it.
