There's an awesome database about lifting, supplements, and everything fitness found at bodybuilding.com
Their excercise database can be found here: http://bodybuilding.com/fun/exercises.htm
They've got videos of how lifts is done and well written descriptions, including breathing for the more complicated lifts.
Articles range from diet, to sprint training, to lifting and the like.
Just note that you will find information that is more towards bulking up and looking good, rather than building athletic strength and quickness. Just know what your looking at because their are things such as how to utilize isolation excerises to create the most pumped looking muscles for a contests or something, and that really has no benefit for sports.
But there is so much good stuff ranging from improving your 40, to verticle jump, to whatever you need to improve.
As far as nutrition goes I have to say bodybuilders seem to have the most well kept diets of any athletes. I've have been "inspired" to better what I'm eating to improve my performance. I also like because you can get the basic run of the mill explanation for the reasoning behind something in nutrition but they break it down as if it was a high level biology class as well.
