Bulk Rename Utility is a useful freeware tool for renaming multiple files at once. It has many options for how to rename the files - you can search and replace text, insert prefixes or suffixes, insert incremental numbers, and more. The GUI is somewhat intimidating at first, but it really is rather simple to use, and you can preview the new file names based on your selections to make sure you have them right, before doing the actual renaming.
GoldWave is a NON-freeware audio-editing utility. It has some neat features. The noise-removal option works well for removing hiss. The pop/click removal option does not seem to work very good - at least not when I tried using it to remove all popping noises from some tracks I had transferred from records. I purchased this program back in 2001 when I was doing some audio stuff, and did not think my license was good anymore, but according to their website, it may still be! I submitted a request with my old info, for a new license ID, and will see if I get it or not.
