OK, not a photo pro or anything, but I'll chip in my 2cents.
Take a look at 3rd party RAM from NewEgg or Crucial. You can probably afford to add another gig if you don't have Apple do it for you. You can snag a stock machine with no wait that way as well.
Take your old copy of XP, install it on your Mac Pro and run the Windows version of PS on that 'till the Universal version arrives. I'm not sure, but I would guess that PS will run well with Parallels (it doesn't need the GPU, so shoudl be near native speed right?) meaning no reboots or anything like that.
Next year when CS3 comes out, assuming the use Core Image and what not you can snag a new/used video card and get all the crazy speed the MP has to offer.
Hope that helps!
