No. For one thing,
mage should be executable. Also, your database password is in app/etc/local.xml, so you want to make that not readable by world. You don't really need
find to accomplish setting the permissions. From the mage root:
chmod -R -x . # remove execution bit from everything chmod o-r app/etc/local.xml chmod +x mage chmod -R ug+rwX . # make files read/write, dirs rwx for owner and group
This doesn't reset the permissions for other users other than for app/etc/local.xml.
Yes, those commands are technically correct in terms of using chmod to affect those changes.
The permissions you listed are fine if the server you are on is running PHP / the webserver as your FTP user, and all files and directories are owned by you. This would be the case with php-fpm, or PHP as a CGI and using suphp.
If however, your host is running PHP as mod_php, and Apache is set to a generic "nobody" or "www" user, then a few directories (recursively) need to be world writable (chmod 0777):
