Best advice -- find a local running club that does track workouts. The group dynamics will be incredibly helpful as a baseline. Sprinting is big on strength low on endurance, that's why you see muscular sprinters and lean 5k+ runners.

IMHO the biggest factor at being fast is training fast and understanding this is a multi-year effort not a quick fix. Odds are you will need to change slightly your foot strike pattern, this is a long term project, not something that's done in a month.

Good luck.
