Assuming you are happy with your code so far...
A longhand line by line removal of the trailing space.

You need to run find again to get at the new folder name.

So does it make sense then for me to run the script with loop that first goes and changes all of the folder names and then later in the script another loop that then goes through and changes all of the files? Something like this:

Code:
find . -type d -iname "* *" -printf '%p\0' | while IFS= read -r -d '' FN;
do
        FNnew=`echo "${FN%${FN##*[^ ]}}"`
        echo "$FN" "$FNnew"
        mv "$FN" "${FN%${FN##*[^ ]}}"
done

find . -type f -iname "* *" -printf '%p\0' | while IFS= read -r -d '' FN;
do
        FNnew=`echo "${FN%${FN##*[^ ]}}"`
        echo "$FN" "$FNnew"
        mv "$FN" "${FN%${FN##*[^ ]}}"
done

You could do the files first and then the directories, like so:
Code:
{
  find . ! -type d -name "* " ......
  find . -type d -name "* " ......
} |
while  ...
do 
  ....
done

@RudiC, vipertech:
Also note that it is best to use quotes around the inner expansion so that if it contains characters that are special to the outer expansion they will not be interpreted as such:

Code:
mv "$FN" "${FN%"${FN##*[^ ]}"}"

My two loop idea doesn't work anyways because it still will not find sub-folders of sub-folders already renamed.

Try find -depth, which will process folder contents before the folder itself. This should avoid cutting off the branch you are standing on, so to speak.

You could try find with the -depth option
