Bodies come and go, but lenses are forever. If you have your heart set on going FF, I would invest in lenses that will eventually fit your need then. Otherwise, you will be in a situation of needing to unload the crop AND lenses, and who wants that hassle? I don't see the economy picking up, all this unemployment makes me very uneasy as a whole about the country's situation. Consequently I think limiting any needs to sell in the future is better.
Insofar as the 16-35, I rented it last summer, but used it on a 1.3 crop, not a 1.6. I fell in love with that lens. It is a beauty. (I am deeply considering a purchase while rebates on it is in effect). However, I am unsure how well it will do on a 1.6 crop. Because of the money investment involved, I would bring your camera to a shop to physically test the pair together. While you will be investing for the future, you also need to make sure that while you have the crop camera, it has to function well together for you.
Another option out there - if you really want to go FF - I have seen alot of 5D used bodies in this same price range - true you won't have any money left for lenses - but you also could unload the crop and try getting at least one lens to fit the used 5D.
Hope you find the solution that works for you.

you could get that one and save the rest of the money for something else. Or get a 50mm 1.2 but then you need $200 extra
, the 17-40, the 16-35, and the 85. See how i like them and make my choice then. If i dont like the purchase i made i can walk back to B&H and return within 30 days of use. Thats why i love that place!
