I'd say the 70-200mm f/2.8 would come in as the most appreciated, but it depends on your shooting style. If you like landscapes, go wide angle. If you like sports, wildlife, or just shooting faraway things, get the 70-200mm.
The macro lens and the tilt-shift lens both occupy a small niche of photography. Once you go out of that niche, you will have to think of creative ways to use them. The wide angle zoom is a little more versatile, but if you want the most bang for your buck then go with the tele.
If you do go for the telephoto, try to get one with VR in it. You will appreciate it a lot.
I am in a similar situation as you, except on the Canon side. I have the 24-70mm f/2.8L USM (which is an awesome lens in and of itself). The next lens I would buy if money was no object would be the ~$2200 70-200 f/2.8L IS II USM. Then probably the 17-40mm f/4L USM (over the f/2.8, because with wide angles and landscapes, one stop of light won't really affect me).
