i jus remembered to add: I have disabled the windows xp firewall and I use mcafee personal firewall. It makes no difference if I disable mcafee or not.

Well, I wouldn't disable McAfee. The average lifespan of an unprotected Windoze box on the 'Net is about 20 minutes. After that, you can reasonably expect it to be h4x3d and 0wn3d by some script kiddie in Peoria, or maybe Prague. They'll have your 'botted machine participating in DDOS attacks or sending SPAM before you can say "Blue Screen of Death". Hopefully you didn't have it unprotected long enough to be zombied (and yes, with SP2, its still vulnerable).

The 192.168.x.y address is your "private", non-routable IP address, probably the one used by the other computers sharing your Internet connection. The other 82.z.z.z  address is your "public", routable IP address, probably provided via your ISP. Its how your primary computer talks on the Internet.

I'm not familiar with CivIII (I used to play the Civ board game) - are you sure its listening on the Internet address, and that its ports are open? I have no idea what ports it wants open - consult the documentation.

ok, i found out how to open ports, but when i go to open 1, i get a big list of options:

Program Name
Program Category (greyed out)
Incoming TCP/IP Ports
Outgoing TCP/IP Ports
Incoming UPD Ports
Outgoing UPD Ports

how do i know which of the 4 port slots to put the port nuber in?

If you open the ports in your machine's firewall but people outside your network still cannot connect, your ISP may be blocking one of more of the ports. Ask them what restrictions are on your connection.
