Find the best youth coaches you can. Tick the box in the team policy that says, use current first team tactics. Every now and again, play them in cup matches against weaker sides. Send them out on loan. As far as training goes, make your own schedules focusing on how you want your team to play. If you have a similar player who is reaching the end of his career, get him to tutor the youngster. If you have the money and they aren't at a good enough standard already, upgrade your youth facilities. The weakest important stat for the players position, put as the individual focus. Also, I think there's a thread for training schedules if you search. Hope that helps.
