If your worried about the 5d being replaced within the next year, try finding a used one. Or go with a 40d or 30d and put the money into good glass until the new model comes out, which may be a while. There isn't a lot of reason for canon to replace the 5d any time soon. Probably the most compelling reason to buy a 5d is because of the full frame sensor. The 40d, as i'm sure you know has the smaller sensor. And I don't know of anyone else who makes a full frame sensor camera besides Canon. So, there really isn't any need for Canon to upgrade it right now. When sales of 5d's drop off enough, then they will replace it. The 30d, however, had strong competition from Nikon, and to a certain degree, Sony, Panasonic, Olympus, and everyone else. So, they had to keep up, so here comes the 40d.
As for lenses, I bought a 28-70 L and a 70 - 200 2.8 L non IS. If I had it to do all over again, I think I would have bought primes. I personally, with what little I've done, have found that i would like to be further back from the subject when doing a close up shot. I don't really know how a longer then 200 mm lens would work for a close up. the 85mm L lens is supposed to be the be all and end all of portrait lenses. The 135 is supposed to be good too. I would love to know what others use for their "if I have the room" lens. If you go with a 40d and use the standard "fits all Canons" lens, you will get the 1.6 multiplier effect, which will make your standard 50mm into an 85mm (abouts).
