Serious Privileges Problem: Please Help

restorecon didn't change ls -lZ output
Can you give me the exact command for chcon? It complains there are too few
arguments, and I couldn't figure it out.
Does this really matter? I moved the selinux folder and its contents as well
as sent an "echo 0>..." command to kill it. Furthermore,
[root at 13gems global_solutions]# ps wax|grep selinux
17645 pts/0    S+     0:00 grep selinux
Please advise.
