Welcome to the forum.
I assume your looking for best HDR settings, well the bad news is there is not one set of best setting to use.
The import thing about HDR is the only setting that can change is shutter speed, everthing else must stay as it is. Don't have any movement in the image otherwise you will get ghosting of moving objects.
Use the histogram to ensure you have captured the full dymanic range of the scene.
I have been using Photomatix (free download) to process my images but how you do it is down to you and experience I'm afriad.
Good Luck any other questions fire away.
If you want to edit any of my images to demonstrate points/techniques to either myself or others please feel free to do so.
Still learning with Canon 40D, 28-135mm, 100-400mm L and Elements 6.
Any Advice greatfully received.
