With a chicken drumstick, you could probably just give him bits of meat off it (in a shape that he could pick up) or the bone... the whole drumstick might be a bit heavy and awkward at that age.
As for the pasta... just give him some to try. It's all about letting your baby learn about the food (texture, taste) and also letting your baby learn how to get food to his mouth (even the really slippery, awkward stuff, lol).
