Just my two cents...
It's not quite as bad as it sounds; lots of programs don't just rely on the filesystem execute permissions, but also check that they're being run by root as well. Unless the setuid flag has been set on root owned executables, you probably aren't too shafted.

As a start, setting chmod 755 /bin/* /usr/bin/* /usr/local/bin/* will be safe enough. You may want to be more careful with /sbin/* and /usr/sbin/*
