For that price range I'd look into the Canon Rebel XT/XTI with kit lens. Kit lens would be good for general shooting and landscapes.
Add a 50mm f1.8. It's a great portrait lens and awesome for the money (sub $100 for the Canon I believe). The 50mm f1.8 will also work great for sports in lower light or indoors.
Then add the Sigma 70-300 APO DG Macro. (around $200-250). This lens is a real bargain and very, very sharp stopped down to around f/8. In bright days outdoors, this would be a decent lens for sports. It would also be good for closeups and general animal photography. As the topper....it has a wonderful 1:2 macro feature which will be great for macro's. It gets me closer than I need 90% of the time and again is very sharp.
All of that should run you around your $900 mark or so. That is actually the setup I have in NIkon and it is a great way on a budget to cover all the range you need and get really good quality pictures in most situations.
