If you want to upgrade soon GTX 275, then SLI when ya feel like you want it. But IMO I would wait until GTX 3xx series. 8800GTX SLI still handles itself mighty well at 1920. I don't think GTX 275 will quite match up with 8800GTX SLI but once you get a 2nd you'll be flying circles around em.
If you want superior performance in 1 gpu you might have to wait until the next series...
As for the rest of your system it looks fine. C2Q @ 4.2 ghz still handles games plenty fine, and should for a while.
If it's running fine right now then I'd wait for the DX11 cards. The only single card that would give you as much performance as the two of yours would be a 4850X2. As far as single GPUs even the might GTX285 is generally a little slower than two 8800GTX cards in SLi. The only real upgrade for you right now would be the GTX 295 or a 4870X2. With the GTX295 you can get one now and add another latter (since you have an SLI board).
