Fan though I am of the XTi as far as I am aware the only kit lens this camera comes with is the EF-S 18-55mm. Not sure how close you expect to be to the action but my guess is that 55mm (full frame equivalent of 88mm) won't get you close enough.
On the UK site Nikon mention the D40X High-Power Zoom Kit
which includes the AF-S DX 18-135mm Nikkor zoom lens. Nikon fans would be better judges of this lens than I but with an equivalent zoom to 200mm I would think this might be a better option.
Alternatively, there have been a number of threads on the forum which have discussed the pros and cons of purchasing an older model camera body and using the money saved to get the lens you need. Remember that you can always upgrade the body in a few years time and, if you stay with the same maker, use your lens collection on the new body.
