Those are two curses based programs that give you ability to start and stop services (ntsysv) and configure your firewall. (lokkit). However, ntsysv seems to only affect rc5.d not rc3.d at least on a recent version of CentOS.
The services you mention are all for sharing via NFS. If you're not using NFS, you don't need them. There's a good explanation of many of the services automatically run at boot here.
To turn them off completely, you might want to use /sbin/chkconfig, for example
/sbin/chkconfig rpcbind off
It's unfortunate that there isn't any easy to find documentation about each service by simply doing man <servicename>. It seems one has to google for half of the services started by default.
