iptables question



I was wondering about how to change or add rules to the iptables.  I
read the man page for it but can't seem to quite grasp the concept
apparently.  Here is what I get from an iptables -t filter -L:
************************************************************************
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
RH-Firewall-1-INPUT  all  --  anywhere             anywhere
 
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
RH-Firewall-1-INPUT  all  --  anywhere             anywhere
 
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
 
Chain RH-Firewall-1-INPUT (2 references)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere
ACCEPT     icmp --  anywhere             anywhere            icmp any
ACCEPT     ipv6-crypt--  anywhere             anywhere
ACCEPT     ipv6-auth--  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere            state
RELATED,ESTABLISHED
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:https
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:ftp
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:ssh
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:5801
ACCEPT     tcp  --  anywhere             anywhere            state NEW
tcp dpt:5901
ACCEPT     udp  --  anywhere             anywhere            state NEW
udp dpt:5801
ACCEPT     udp  --  anywhere             anywhere            state NEW
udp dpt:5901
REJECT     all  --  anywhere             anywhere            reject-with
icmp-host-prohibited
*************************************************************************

I would like to change the settings for the ports for ftp, ssh, and VNC
to only allow connections from 204.99.118.0/24 and so far this is what I
have:

iptables -t filter -R RH-Firewall-1-INPUT 9 -p tcp -s 204.99.118.0/24

All that does is produce an output similar to this:

          tcp  --  204.99.118.0/24      anywhere

Can anyone help me with what I am doing wrong?  How do I add the ACCEPT
and the state?  I have tried --state but it keeps telling me that it is
an incorrect option.
