unix/linux chmod to let everyone read every directory and file

I'm having file permission trouble backing up my MacbookPro through my LAN to my Windows computer.

I want to set permissions of all files and directories on MacbookPro to allow reading by all. On the Mac, I've been using two accounts over the years, so some files have this permission, some have that.

So I need to do: chmod -R a+r *

Also, I believe I also need to do a+x for all directories: chmod -R a+X *

Which means I can do both with: chmod -R a+r, a+X *

Is this correct? I'm asking so that I don't mess up access to my HD.
