For 3 you can also add the following if you agree with me of course:
Creative player needs to be given room to be affecting hence he should not given intensive closing down
Be careful when instructing players to do "forward runs" often as this can drag the player out of a vital position defensively.
Keep the tactic balanced in that even if all the players can run with the ball that doesn't mean that they should. They can be intercepted while in possession leading to goal scoring opportunities for the opposition .
I know some of these are basic tips but it should help out anyone new to the game
