Re: What would you do if you had $2000, a 5DII and no lenses?
Be both very sad and very excited? After all, a body without a lens is like frying pan without a stove. It may have some alternative use, but for its main purpose in life...
I would buy a 24-105L, put the remaining $1300 in the bank, and start taking pictures. After say 6 months, you'll know if you need for your next lens to be a telephoto lens or a wide angle one.
If you need a wide one, buy the 17-40L, and you'll still have $600 for something else. If you need a longer one, I'd recommend the 70-300L IS, which will be about it (you might even need a few dollars more).
As I've posted before, my order of priority was:
50 f1.4 Zeiss
and next on the agenda is either the 17-40L or the 16-35L MkII, then a 100 macro L
But that's just me
