Would a good UV filter help with CA's.
I know most software packages can fix the problem post production but would a really good UV filter not help with the initial image? If so any recommendations?

CA is caused by the lens. The filter wont have any affect on it. At best, a good filter makes no difference at all. If you really don't like creating CA in the first place, the only thing to do is change lens.
