Are you using the option on the Output tab to use multiple CPU cores, if available to you?
To enhance detail you might look at using one of the filter Action options: possibly Focus restoration, Enhance focus, Sharpen or Unsharp Mask. Adding a filter will of course slow processing slightly, so you may have a trade-off there.
You could probably more easily assess the effectiveness of particular filters in the editor rather than in the Batch convert, as the displayed images will be larger than the preview in Batch convert.
Maybe someone else can comment on your other points?
Are you using the option on the Output tab to use multiple CPU cores, if available to you? - NO...Thanks for the pointer. I have a Quad core iMac. Will this speed things up? Will it slow things down regarding other running software?

I don't have the technical background to give a definitive answer, but I would assume that even with all cores selected the operating system would still allocate resources to other running programs. As many everyday applications such as web browsing and word processing normally only require limited processing on a modern computer, you might not notice a significance increase in processing time unless you wish to do video editing or complex spreadsheet calculations at the same time...
