Mind you i think if i were to upgrade it wouldn't make my shots better but rather crisper and sharp to look at. Even when my shots are in raw they're shocking, so if you know anyone wanting to buy a camera tell em mine they can buy!! lol
Generally there isnt too much difference in terms of sharpness in any of the cameras, it only becomes a problem when there is a problem with the camera. A lot of people sharpen up their images in post process, so this may be one of the reasons that you find other peoples' photos are sharper than your own. Other things that can affect this include: lenses (some lenses are just sharper than others), camera shake (esp with long exposures) and focus accuracy. Unless you apply sharpening, your RAW will be inherently softer than jpg as the camera applies sharpening when you use jpg.
If you really think your camera has some AF problems then I would have a look at taking photos of a ruler from a 30-45 deg angle with the lens wide open and zoomed to a longer focal length, using a tripod with image stabilisation off. If you aim your focus at one point then shoot you will be able to see if the focus is in front or behind where you are aiming. Keeping the aperture wide open and using a longer focal length will keep the depth of field shallow. This is a quick and dirty method (best done at the minimal focal distance of your lens with a telephoto), but if you want to be more precise there are specialised charts and tools that can be used.
PS your camera would be welcome over here, if it needs a new home, I quite liked the E-510 when I lent one.
