ps is in /bin, top is in /usr/bin ; unless you a) have your PATH wrong
or b) commonly put /bin on separate file systems, you should be able to
use ps and others in /bin and /sbin.

Are your world and kernel matched?

When you enter single user mode, root file system is mounted read-only
so one of the first things you need to do is "mount -u -o rw /". Next,
you need to mount your other file systems (/usr is usually a separate
file system and that's where ssh lives) so do "mount -a". At this point
you might as well cancel the single-user mode by exiting the shell and
go multi-user.

If there are file system errors. "mount -a" will fail and you'll need to
mount other file systems by hand.
