[Help] Updating and setting up a private lan server

[viperguts]

I am a newb to private servers. I have wow and tbc patched to 2.4.3. I have the retail of wotlk. I would like to update all to
3.0.3 and start a private server for use in a lan. I downloaded some patches from filefront and another place.
They are: wow and tbc 2.4.3 - 3.0.1
and 3.0.1 - 3.0.2
and 3.0.2.9056 - 3.0.3.9183


How do I update my wow installation? I only have wow and tbc to 2.4.3 installed so far. Also is there a verification check when updating using
the downloaded files. And are these directions and files all I need to setup my server?

Aside from Hamachi, I know how to set that up. I am also familiar with static ips and port forwarding. The rest is just knew to me. Thanks for the help. Please point me to the info if it is already posted.

Nevermind I figured it out. Now I have to decide a 3.0.3 repack with WotlK.
