point 1 and 2 are ok for the beginning.
3. A young player with a high potential is the best player to train. If you have such a player, consider including him in your oppening five, even if he is not the best player for that position, and define training accordingly.
actually i don't think that potential is so important like good starting skill, at a trainee(you could train allstars pretty far).
And he should not start every game, it is important to rotate much on trainingsposition to give a lot of players around 48 minutes playing time. To use this minutes good, you should buy other young players.
4. Define your tactics to benefit from your best players. If your Center is the best player, it might be wise to play low post or look inside, and vice versa
Look at the ratings from the opponent, and try to exploit his weakness ... At the beginning you should be able to play all tactics, maybe later your trainee force you to play other taxctics.
