Making a server with mods is a huge pain! Go to bukkit.org and download their latest server if you haven't already, makes it much easier. As for the error report, I have no idea what any of that means. In my own experience with vanilla server running, the one thing to be wary of is port forwarding. If you need help with port forwarding, go here: http://portforward.com/english/routers/port_forwarding/routerindex.htm

Any help that the server is in 1.6.4?

Are you running 32-bit or 64-bit Windows? For 64-bit Windows you might specifically need to manually download/install 64-bit Java, because the default Internet Explorer is 32-bit, so by default only 32-bit Java is installed from that.

Looks like an lwjgl error which should not even matter for a server unless trying to launch it with gui without proper GL support or something. Maybe try launching it with nogui at the end of the line that launches the minecraft_server.jar (or if a modpack whatever.jar launches that).
