iso 100 ,200?
If you're taking pics of people or moving things, ISO800 and above (ie 1600, 3200 etc).
If you're taking pics of landscapes, it depends on the shutter speed you want. If I had a tripod and I wanted a 15second exposure, I'd go with ISO100 - 200. If I wanted a 3 sec exposure, then maybe ISO800, for example.
as low as possible to get the effect you want
there is no magic number to follow
it all depends on the lighting situation there and the effect you want to achieve
For low noise night scene image, usually the lower the ISO the better, that is you have a steady platform or tripod to hold the camera. If not, higher ISO will be needed to reduce shake. As other mentioned, For other special effects, different setting may be required.

choose a subject take as many pics as u like with different settings than do ur own comparisons....thats the beauty of dig cams...wont cost u a cent....unlike the olden days of film photography when u had to pay $$ to get ur pics printed.....
Dont look at ISO, but at the possible shutter speed possible.
For example, in a dim light area such as hawker centre, minimium as per norms to have movement blur, a 1/50 and higher is needed. Probly ISO 1000 is needed here.
Even dimmer, i dont mind going all the way up to max ISO 3200 or 6400 as long as i get that speed as a reference. After all, if you dont like noise - shoot RAW and process with Adobe Lightroom for it's handy & accurate NR function.

Noticed you have not stated your camera, not all can handle high ISO and RAW.
Scenery with still life, tripod and ISO 100(or L1.0), as long exposure as you required. No tripod, don't waste your effort if you can come back again. If it's night time, whu ain't u with a tripod if you know u want to take such a scene ? Impromptu ? I think you can wait for your 2nd chance.
Moving targets like people and portraits, well bump up your ISO aim and shoot.
