Yohan pretty much has teh corr3ct. I'd just add some agility drills to make it even more awesome However, you need to think about how to space your workouts, what types of exercises you choose to do (eg. plyo, I'd be hitting that hard on the first day of the week but only doing it once a week). Time your runs, keep a log of what you do, your results. Recovery is obviously very important. After I started lifting for strength and combining that with plyo and my cardio I found my foot contacts to ground increased, my explosiveness, speed etc. all benefited from the wholistic approach.
Depends on whether you mean straight line track sprinting or dynamic speed where you will change direction. www.higher-faster-sports.com is a great site with loads of free articles on this kind of thing.
Im confused. This article says extensor dominant squats are better for sprinting. Which I take to mean back squats superior to front squats for speed http://www.bodybuilding.com/fun/kelly20.htm In this article they say front squats are better for speed. http://www.t-nation.com/readArticle.do?id=1736931 The answer is probably both benefit. I think the best exercises would probably be front squats on one leg.
Technique I got the opportunity to train with some local level athletes and they all run fast because they have a good running technique - GPP came into it but they work more time on the track then they do in the gym.
