telnet is generally considered insecure
and has been more or less replaced with ssh
so you really should only need sshd.
but if you insist
you'll need telnetd installed to set up a telnet server

as for an ftp server
i recommend proftpd
since i've heard that wu-ftpd is rather insecure

as for what happens after the packages are installed
i'm not sure
since i install proftpd from source
  www.proftpd.org
