If I may jump in Jonathan, if you don't really need that smaller, lighter camera body option the D700 provides, by all means go with a D3.
The D3 has a better finder, an even tougher body, better battery life, better handling with bigger lenses (and smaller ones in regard of shooting verticals) and in my opinion the best dual card slot option: 2 identical CF card slots, none of that mixed slot thingy nowadays in fashion.
If a D3s is in your budget, it offers some serious improvements over the D3, making it worth a second look.
For me the biggest + of the D3/D3s is it's rear LCD for quickly setting and checking ISO (I always shoot manual ISO and quickly setting and checking it with a glance on that additional LCD is priceless.
The D3 has one downside to the D700 though: you will end up cleaning your sensor more often than with the D700.
Another option to the Noct-Nikkor which I find myself liking a lot recently is the new 58/1.4 AF-S.
Simply ignore the naysayers who stamp it to be a hugely expensive marketing Noct. It is a wonderful lens with a lot of character similarities to the Noct. It is less than half the cost new to a Noct nowadays and it is it's higher price worth over the pedestrian 50/1.4 AF-S (I never liked the 50/1.4 AF-S).
If it's your cup of tea, you can wait a little more and see those D800E bodies falling in price on the second hand market as people storm the shops for the D810, but that is a lot of data to move around you might not really want or need.
If you plan to shoot manual focus lenses, there are screen options available from different manufacturers.
I currently like the most a modified Canon Precision Matte screen, you can buy from
focusingscreen.com
This screen is blank full matte and you can focus anywhere in the finder.
It is so far the only manual focussing screen I tried with the D3, that provides better precision with a f1.2 lens (I find it better even than Nikon's full matte screen for the F3).
