Mel,
According to the man page, using a+X (note the capitalization) should
only set the executable bit on directories, or on files which have any
executable bit set. A quick test confirms this behavior. I think
that the combination of the two commands that Zbigniew Komarnicki
listed will result in the desired permissions for the subtree.

Naturally that's u+w.
I shall proofread before pressing send.

That's the equivalent of chmod -R 755, since it sets exec bit on everything.
Assuming all directories are already executable and files are not, the
shortcut would be:
chmod -R o+w,go-w,a+r /usr/local/www/data/wp

Maybe also in such way:
# find /usr/local/www/data/wp -type f -exec chmod 644 {} \;
# chmod -R a+X /usr/local/www/data/wp
of course if you have symbolic links there see for additional options in chmod
command as for example -L, -P, H.

And special characters in the filenames aren't a problem since "find"
passes the arguments directly to chmod as an array of null-terminated
strings, so they don't get interpreted by the shell.

Oh? Safer how? I've never come across that idiom before.
If imange the file or directory name has spaces, (){}-, etc.. in
it or even \.
This is not necessary with -exec in the 'find' command, and the
single-quotes wouldn't have any effect. The {} is a parameter
which is seen by the find command itself. If you add single-quotes
around the {}, those quotes are stripped off by the *shell* before
handing the parameter off to the 'find' command.
Dangerous characters are more of an issue if you do not use the
'-exec' option, and instead you have 'find' print out the filenames
and then use those filenames with some other command.

Why the single quotes around the {} ? I don't think I have seen that before
and I want to understand it before I save it in my notes. I have often
wanted to perform the same task but I did not know if there was a way.

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;
You could also probably use mtree but you'd need to make the config file
first.
