Permissions (or something) got broken, can't find a fix

I was trying to install the printer driver for my Samsung printer that I got from Samsung's website some time ago.  I first tried to install it from user account using sudo, but noticed that it changed ownership and permissions for /lib64, /etc and /usr.  I then tried to install it from the root account, and noticed that it changed the permissions for the same folders again (though it kept ownerships as root:root).  I tried to change everything back, but I must have missed something because I can no longer log into my user account, nor run any commands from areas that are logged in already.

I can still log in as root.  When I try "su user", I get the error "su: /bin/bash: Permission denied"

I've installed the Samsung driver on two other Linux machines, one Arch and one Ubuntu, and never had problems like this before.  Can anyone help me clear up this problem?

Some additional information:
