I am graduating from my SD600 to a DSLR for a 4.5 month trip.
...
I am planning on buying the body only.
I won't comment much on XTi vs XT. Yes, the XTi has a better autofocus, anti-dust mechanism, etc. But I don't know how much value you put on those differences compared to the $160 price difference...
It was some other things about your post that bothered me, though.
First, I can't tell from your brief post whether you understand these things, and apologies if you do, but if you buy the body only then you won't be taking any pictures. You need to think carefully about buying a lens or lenses. The lens on your SD600 is roughly equivalent to 22-66mm on an XT or XTi. A popular lens in that range that delivers a lot of quality for the money is the Sigma 17-70mm, but there are loads of others. People here on POTN can help you choose if you need help.
Second, you need to know that a DSLR like the XT or XTi has a long learning curve. You can't expect to just pick one up and take good photos with it. If you don't have time before your trip to get really familiar with a new camera, it might be a better idea not to go down the DSLR route just yet.
Third, an XT or XTi won't take the same memory cards as your SD600. They both take CF cards.
Fourth, if you're going away for 4.5 months then you'll presumably take a *lot* of pictures. You'll need to think through your strategy here. How many gigabytes of CF cards? Will you be visiting places where you can upload your pictures to the web, and if so how regularly? Will you be carrying a laptop for downloading? And so on. I have 5x 2GB cards which means I'm good for up to about 1200 photos on one trip with my 350D (XT).
Fifth, you need to think about batteries. The XT and XTi use a chunky lithium battery called an NB-2LH which is not compatible with your SD600. The cameras come with one battery and an AC charger, but if you're going to be going places where the electricity might not be reliable and/or if you might be taking *lots* of photos and/or if you're going somewhere really cold, then it would be a good idea to get a couple of spares. Canon batteries are pricey but a company called Sterlingtek makes very good ones much more cheaply. I carry two spares with me.
Hope that helps. Apologies if it was all stuff you already knew. If you have any more questions, you've come to the right place.
