I would do it the same way you do, but with xargs instead:

find . -type X -print0 | xargs -0 chmod XXX

If you were feeling crazy and use sh:

find . | while read path; do \
   if [ -d "$path" ]; then chmod 755;
   else chmod 644; fi; \
done

The latter is overkill, but the approach can be useful for nontrivial 
operations on systems that don't support -print0.  It also has the 
benefit that you can do it over ssh without having to copy over a 
script, e.g.

ssh user@host sh -s <script.sh

(No nightmares from having to double- or triple-escape special 
characters, either.)

Sorry, I don't know how to do it all with chmod.  I assume you've 
consulted the excellent FreeBSD man pages?
