Unfortunatly the Tamron digital lenses will not work on the 5D or 5dMKII nor will the Canon EF-S lenses such as the 17-55 f2.8 IS.
The 1DMkIII is still a crop body (APS-H) and the the 1DsMKIII is FF.
There really are a lot of options but with out some budget it's next to impossible to offer much meaningfull advice. If the skys the limit then I'd be dropping 6k on a 500 f4IS for wildlife toot sweet!
My choices would likely be a 17-40L and a 100-400 to start simply due to the price point. Another option would be the 24-105 and 100-400 but then you really dont have a wide angle lens, however you have a good starter wild life lens and a great standard walk around zoom. Other choices might be the 16-35 or a 24-70. If your not shooting indoors then there's no need for anything faster, heavier and more $ than f4 glass. Theese are specific lens pics and not just focal length suggestions. If you consider standard EF glass or third party glass you need to evaluate each lens as not all are created equal.
