I just downloaded Professor Franklins instant photo effects from //www.tucows.com. It also does some lighting effects (among other things). Its 30 day shareware and after that costs $29.95. its worth a try.
I just love that everyone shares good info on this site.
I have a book that I just got at the library that I think is excellent:
Creative Digital Photography by Michael Busselle. I think most libraries would have it.
