Not sure when to choose between 100, 200, 300, 400 ISO

Any general guidelines would be appreciated!

Simple answer is to use the lowest ISO you can get away with for the situation...
Using a higher ISO means the sensor/film is more sensitive and so needs less light... now this is good in that it means that you can use a faster shutter speed thus reducing the posability of motion blur, or a smaller apeture giving greater depth of field etc.
The problem however with using a higher ISO is that the resulting image will look more grainy/noisy.
If you want very crisp images with little noise or 'graininess' then you need to use a low ISO
I normally try to use ISO64 on my Fuji S5500 unless the light is getting low then I might go up to ISO100.
The only time I use ISO200/400 is for a low light snapshot when I can't use the flash (because the flash is distracting or not allowed etc) and I will only do it if I don't really care about the quality, I just want to capture the moment.
Hope that answers your question.
