For wildlife, birds, and sports, your current gear is probably a bit short. Instead of your current shortlist of the 14mm F2.8, 16-35mm F2.8, or 70-200 F2.8, you might find a longer zoom such as the 100-400 F4.5-5.6 IS or the 300 F4 IS more useful. Your ownership of the 1.4X Extender could also be used with the 300 F4 IS to make it a 420mm F5.6 with the 5D MkII or a 672mm F5.6 on the 500D.
Both of these lenses would be more suited for outdoor work but since you have a 5D MkII, which has great low light/high ISO performance, they will also be good for indoor work as well.
