The unix faq describes how to change file names to lowercase
(http://www.faqs.org/faqs/unix-faq/faq/part2/section-6.html).
Changing spaces to underscores in filenames is similar.

This zsh script worked for me:

            for f in *; do
                mv $f `echo $f | tr ' ' '_'`
            done
 
(replaces spaces with underscores for all the filenames in the
directory.)
