disclaimer: you may not get too many pro-Canon opinions on this forum.
the 5D was a good camera in its day, but 3fps would be way too slow for what i shoot. if i wasn't invested at all in nikon, i'd look at the 5d mkII, but you'd be getting a worse AF system than the d7000, plus the price tag wouldn't leave as much left over for lenses.
i think one can easily make a strong case for the d7000 as a portrait shooter and all-around camera.
as for lenses, i have the sigma 50/1.4, but i don't really like 50 on DX for portraits (too short). i'd consider the tamron 28-75 and sigma 50-150 as "DX portrait zooms," and the 58/1.4 voitglander or tamron 60/2 macro as "DX portrait primes." also, the 35/1.8 and sigma 30/1.4 are good for slightly wider portraits on DX, with the 30 having better out-of-focus background renditions and slightly more sharpness. the 24-70 is also good on DX for portraiture, but for the price you could get the 28-75, the 50-150, and the 35. if you're not shooting events, the 24-70 might be overkill to some degree.
