Would any of the photographers on here like to give a little run down of what effect changing the different settings have (ISO, shutter speed, f-stop...). I am specifially interested in being able to take clear, close up shots of both my statues and artwork, usually indoors with artificial light.
Thanks.

I can answer specific question you have big G.
The higher the ISO the less light required to make a correct exposure. Good for Low light or night time situations. However too High an ISO will make the image lose quality.
ISO is the speed of the "film" or at least it did with film. The lower the number the more light it requires to make an exposure, hence the higher the ISO requires less light and is more suitable for indoor lighting. However the higher the ISO the more noise you will have in your image depending on your camera.
Low F-stop Number allows for selective focus like with Vindicator here.
F-stops will control the amount of light coming into your camera. This will determine the depth of field (how much of the background and foreground are sharp and in focus compared to the subject)
The lower the F-stop the more selective focus you have, so if you want to just focus on one part of the image and let the foreground and background fall out of focus you want to use an F-Stop range from f1.8 to f4
Most lenses are made to work best at a range of f5.6-f11 this will give you a good amount of depth of field and focus. These ranges work best for when you want the image to be overall sharp and focused.
So remember the higher the f number the more depth of field.
Once you start using anything greater than F11 (but if you're shooting indoors or with lights that aren't flash units you won't need a high f-stop) You are getting the highest possible amount of depth of field. However using an Fstop like f22 you'll have the depth of field but you will lose some of the sharpness. But I wouldn't worry about using higher f-stops if you're just shooting indoors.
Shutter speed will capture motion, like the water here. Although this was done with multiple flash units indoors its possible to capture motion outdoors with a fast shutter speed.
Shutter Speed This is the duration of the exposure. The less light you have the longer the exposure you'll need. Indoor lighting will require longer exposures, the longer the exposure the more movements will be blurred. Also if you're hand holding your camera long exposures will make your shot be blurry because your hand moves even if you think you're being steady. If you're using a shutter speed greater than 1/30th I would highly recommend using a tripod.
The shorter the shutter speed (shorter the exposure)
the faster it is the better you can capture motion without a flash but these quick exposures require quite a bit of light. But again if you're shooting indoors you don't have to worry about it.
OH BTW these are my pictures, please don't steal them.
