On the subject of the file-naming conundrum, you might find http://www.bath.ac.uk/idmrc/themes/projects/diak/erim_filename_convention_v10.pdf helpful. This approach provides a contextual framework for file naming which is infinitely customizable. I designed it for an 11-university research collaboration to keep the project output manageable. It turned out to be very powerful and has been used successfully since both in academia and business.

You might also think about the rehabilitation of the ‘title’ as a means of organizing your information- or data-objects. The filename is, or should be, a unique identifier that gives a context to the record; it is not unlike an ISBN number in this respect. Now, how many books have you ever seen that had no title, but were referred to only by their ISBN? Not many I guess. The use of file names and titles together more or less solves the ‘what the heck did I call it?’ and ‘ooh; I wonder what’s in there?’ approach to file management. And finally, if your operating system doesn’t support organization of data records using titles as well as file names you might wonder what good it is.
