The 350D and 400D are very similar I think.
I use to think that perhaps longer exposures in lower ISO would provide benefits, but if you Google for graphs of noise/ISO/temperature for your camera you will find I think that ISO 1600 will be optimal for your camera - shorter exposures at higher temperatures and longer when it's colder.

My experience with a 400D was very similar, with ISO1600 (the maximum for this camera) and sub exposure times of 180-240s giving the best results:
