Upload & Sell: On
If money is a serious issue, I would look long and hard before buying a 5d3 rather than a 5d2, unless the frame rate and improved AF are very important to you.
I upgraded from a 5d2 to a 5d3 (upgrade cost $1900, after selling the 5d2), and I've never regretted it. But if that sort of difference comes dear to you, I would seriously consider a 5d2 instead of a 5d3. I don't know that, in the real world, you'll notice an IQ difference between the two, and the 5d2 center point provides excellent AF in most circumstances.
As for lenses, I'd prefer the Sigma 70-200 f/2.8 (I had one for many years, and loved it) over the 85/150. For macro, an extension tube does well. But I vastly prefer zooms to primes for my uses; YMMV.
