You can use the file command to see if a file is 32 or 64 bit. I
tested a quick and dirty hack and it worked and it should be easy to
put it in a script and expand it to work with apt-file to see what
package the file belongs to. I don't have an answer for finding KDE
3.5 files, perhaps if you know what libraries it uses you could grep
the output from the ldd command. Putting together a script  that can
do  this would come in handy perhaps some with more experience in
shell programming can think of something.

The one-line command to find 32-bit programs in your path:
for DIR in $(echo "$PATH" | sed -e "s/:/ /g") ; do find "$DIR" -type f
-exec file '{}' \; | grep -i 32-bit | sed "s/:.*$//" ; done
