This is basically an updated post from my previous one: https://photography-on-the.net/forum/showthread.php?t=757077
I am posting THIS thread, to clean up everything I have come up with and rambled about in that thread, and to get some fresh eyes on my "situation."
So my original question was; 5D2 now, 70-200 2.8 IS later? Or 70-200 2.8 IS now, 5D2 later?
I got some VERY good replies, and a lot of good stuff to think about.
The main thought that has me questioning the decision I am leaning towards (Cam first, lens later) is the fact that the 50mm on my 40D, will be my longest lens on the 5D2 (85mm on FF is basically 50mm on crop).
My response to this though, is; My 50mm is pretty much the only lens I use (when comparing between the 85 and 50). I find the 85mm to be a very awkward focal length for crop. SO I would be fine having the 85MM be my longest lens on FF for a while, since that focal length is what I mainly shoot with.
The next point that came up was; Lenses are getting more expensive, cameras are getting less expensive. Another good one, that I will "debate" below.
After lots and lots of thinking, I wrote out [In detail] a plan that shows when I can afford, what.
Either way, I will order the first "item" when the Fall rebates start, and I will order the second one when the rebate is about to end (January). So the prices won't be changing while the rebate is offered, so the second point I brought up doesn't really affect my decision.
So now that I have it fairly controlled (i.e. I have it planned so the prices won't change, no matter what order I buy them in. And I will buy 1 thing in October, 1 in January) it's time for a decision.
I am leaning towards the camera first (still) because I have a wedding to shoot next month, and would LOVE to get some high(er) quality images, and I would like to have 2 camera bodies (yes, it's important).
I will need the 70-200 2.8 IS for the wedding, but I have a local friend who will lend me the lens. This is what is putting me off from buying the lens first, because I have a friend who can lend me the lens whenever I need it, so it makes buying it (first, at least) seem pointless, when I could get an amazing camera...
IN CONCLUSION:
Reasons to buy the 5D2 first:
- Shooting wedding next month, need 2nd body and higher res\quality photos is a bonus
- I don't need the lens all that often. When I do, I can borrow it.
Reasons to buy the 70-200 2.8 IS first:
- No need to borrow the lens.
- Will have the lens right when I do get the 5D2. An awesome pair, straight away.
I basically wrote myself into a corner... But I still need some help\convincing 
Sorry for the LONG post, and thanks in advance for everyone who reads it, and helps
