Depth of field in macro work is very thin, and like David, I recommend that you try much smaller apertures. I never shoot bugs at less than f/11. I usually use f/13. I don't always use flash in bright sunlight, but one way or the other, you need a lot of light to allow you to use both a narrow aperture and a fast shutter speed. With flash, I usually use ISO 200, f/13, 1/125, but the flash lasts much less than 1/125, so the flash freezes motion.
Keeping the bug close to parallel to the sensor also helps, by minimizing the depth of the subject.
The key is getting the eyes in focus. It is possible, but very hard, to do that with autofocus, because either you or the bug will move. A fairly common way to handle this is to get the focus approximately right, then move the camera forward or backwards slightly until the eyes pop into focus. A monopod helps. If you are going to do this, it is best to put the AF on a back button. That way, you won't accidentally cause the camera to try to focus again when you take a picture. Alternatively, you can turn off AF on the lens.
If you use flash, it should be diffused. There are lots of do-it-yourself plans on the web. My current rig is this:
The diffuser is made out of two Coke cans, duct tape, and two sheets of baking parchment paper. You can find this one by googling "lord v" and "coke can diffuser", I think.
Here's one I did in bright sunlight, but I think I used a flash. (Note the black background, which is often a give-away for using a flash when there is a large distance to the background.) It was a windy day, and the echinacea kept blowing around, so I had to take quite a few to get one keeper.
Keep it up. Macro can be very frustrating at first, but it is a lot of fun once you get used to it, and you are off to a good start.
