My set up is as follows:

The /etc/ssh directory is owned by root, group of root and have 755
permissions (rwxrw-rw-).  The files IN /etc/ssh are all be owned by
root, group of root with 500 permissions (rw-------) EXCEPT ssh_config
and any "*.pub" files.  Those have 544 permissions (rw-r--r--).

In _your_ home directory, the .ssh directory is owned by you with your
group and have 700 permissions (rwx------).  The files in it should
be owned by you with your group and have 500 permissions (rw-------)
except any "*.pub" files, which can have 544 permissions (rw-r--r--).

Really, since the directory can only be read by you, all files could be
544 (rw-r--r--).  ssh really is worried about someone other than you
writing to those files.
