DSLR advice for a beginner who has high aspirations?

Hi,

Looks like I am going to add confusion to your decision.

Limited budget -> $1,400
Type of shooting - avow low-light, wildlife and sports

Assuming that the wildlife is big and really wild, ie not in the zoo, I probably want to get a good telephoto so I don't have to stand too close to the animal

And don't think I am going to be able to get front rows seats to a basketball match. And worse, even a front seat won't do for football.

So, I will get a good lens that will carry over when I have more money to upgrade the body and start with a cheaper body to see if wildlife, sports and low-light is really what I want to do.
