Yup! ...the hoses from both CCV valves run directly into the upper and lower holes on the face of the intake manifold (see here).

While you have everything apart, make sure the hoses going from the secondary air pump to the secondary air non-return valves (under the back of the intake manifold) don't have any cracks (part #1 here).

On your parts 4 and 7...I broke that a while ago, too. Even a small air leak like that after the mass air meter will definitely cause it to run a little rough / stumble, especially near idle (when there isn't much flow past the air meter to begin with).
