Stopping down the lens means closing the aperture by a portion...

Stopped down meaning not shooting at the lens's maximum aperture. So it a lens goes all the way up to F2.8, shooting at F4 would be stopped down by one stop, and shooting at F5.6 would be stopped down by two stops.

Normally when people say "shooting stopped down" they are referring to shooting in the lens's sweet spot (i.e. where it's the sharpest), which is usually in the F5.6-F8 range.

let's start

On every lens, you can read the focal lengt in mm (like 28mm, 50mm, 85mm, 135mm, 200mm, etc ..).
You can read the biggest aperture available expressed like this 1:1.4 or 1:1.7 or 1:2 or 1:2.8 or 1:4, etc ...
This value is the widest aperture you can get on the lens. Basically if you use it, we say you shoot "wide open".
But you can choose a smaller aperture (like f4, f5.6, f8, f11, f16, f22, f32). When you choose any other value than the biggest one, we say that "you stop down the lens".

Commonly, the best sharpness and color rendering is obtain when stoping down a lens. Around f5.6/8/11 you usually get the best of your lens on any DSLR.

What i'm going to say isn't very original, but, if you have a manual with your DSLR, you should read it.
Pentax do some heavy manual for its DSLR, but they are quite easy to read and have plenty of information.
I don't say that because i heard often this type of question (forums are made to help everyone, and its great !), but because it will make you gain some time, and you'll be able to play more and better with your DSLR, and so, have more fun
