in Manual mode, yes.  Otherwise the camera will adjust and you'll get 
less Depth of Field.

They're right there in the camera.  Every stop change makes a speed 
change and vice versa.    If the light doesn't change.

Every time you increase the exposure time you need less light to get 
enough light on the film/sensor.  Every time you close the lens down 
you need more light to get enough on the film/sensor.

Your digital camera may be very tolerant of errors.  Mine accomodates 
up to 2 stops underexposure easily when I adjust the images in Adobe 
Camera Raw, but it is less happy with overexposure because there is 
no information in the blown out highlights to recover.
