It's very common that HDRs aren't as sharp. This usually comes from the fact that software like Photomatix will try to correct for movement between shots, either of the camera or in the frame and so you often loose fine definition on the edges of things.
You can minimise this by making sure there is as little movement as possible between your shots. If there really isn't very much movement, you could try turning off the alignment steps and dealing with any errors later on in Photoshop.
With regards to chromatic aberration, it's a feature of the lens rather than anything else. However, when you increase the colour and tonal range of the shots it includes any CA. There are loads of ways of removing CA from pictures. An easy method is to use a Hue/Saturation layer and the eyedropper tool in Photoshop. Select the colour of the CA and just desaturate it.
The only time this is problematic is if you have a lot in the frame thats very similar colour. For me, thats pretty rare.
