marcel already mentioned this but I also recommend sending the camera back. Yes you can fine tune the lens and get correct focus between -15 -18, however you a really at the limit now on adjustment which tells me something is fundamentaly inaccurate in the calobration. I had exactly the same problem, sent the camera back to Nikon, they recalibrated the focus and it came back a completely different camera. It is still under guarantee and the backfocus is a known issue with the d7k.
Lens for sporing events: many have mentioned the standard nikon zooms, but if you are open to third party brands what about the sigma 50-150? This is a constant aperture lens which will also perform much better in low light conditions with a minimum aperture of 2.8 throughout the focal range. Check out the user "shootraw", he swears by his if im not mistaken. I dont have the lens myself but if I was going to get into action photography then I would give this one serious consideration.
