If you haven't purchased your new camera yet, then i would agree with "border all". You can pick up a good 40D for around £275 maybe less, and spend a little extra on the lenses, then if you do wish to upgrade even if its just in a years time, the price of 60ds will likely to be lower but the resale value of the 40D will not have dropped by much.
The 40D is a great camera, have owned one for a while (though thinking of upgrading soon), i have also used a 60d and imo didnt feel quite as nice in the hand as the 40D. Also the controls are pretty much the same on the 40, just losing out on the video.
As for lenses if you were to get a 40D you probably could get either a
second hand 70 - 200 L f4 or maybe even an F2.8 mk 1 which would be a good start for wildlife, though not a huge focal length, very fast focus and crisp images. You could probably also pick up a 50 1.8 as a second lens for other photography subjects.
