My 60D is pretty clean at 1600. ETTR
can help, but look at your current exposure. To use ETTR, you will have to either raise ISO, increasing graininess, or lower shutter speed, increasing the chance of motion blur. I would move to a flash and lower ISO to 400 or so. I know that flash is not always an option.
But I've found that raising the ISO to allow a slight overexposure seems to cause less noise than using the lower ISO and adjusting shadows in post. ETTR isn't always going to work if it results in key highlights being blown out, but if the dark areas are important to the composition, then ETTR by bumping the ISO may be the only possible solution. As you say, flash isn't always an option.
I've shot as high as ISO 3200 with a T1i with acceptably correctable noise. One time, even though I had and was using a flash, I wanted this particular portrait to capture the environment. Even at 3200 the SS was 1/13 at f2.8.
