Seeking DOF advice

After much searching on ML and through Google, I thought my understanding of depth of field and the required settings for my camera were adequate. Unfortunately, the photos I'm taking are still lacking both in depth of field and sharpness. Here are a few photos using an 8 MP Canon Rebel XT and the included lens (18-55mm) set to 18. The camera was set to aperture priority mode (f-16). The model is 12 inches away from the lens front and fluorescent lighting was used. I used the camera's setting for this type of lighting. Camera shake was eliminated by using the timer and a tripod. The first three photos were taken using f-16 and the last two at f-22. Any advice or suggestions are appreciated. It appears my images get grainer with the increase from f-16 to f-22. My problem may be the limitation of the lens used. Would switching to a wide-angle lens improve my depth of field?
