If anyone is interested in spicing up his KB a bit, try one of the mods. The interface mods are in my opinion a must.;)
Oh, and if anyone can tell me which version is the GOG one, i'd be happy!
[And no, i'm not asking for the version number]

Any of these mods give you the ability to move the camera with WASD?

I don't think so, but does this help? ;)

Does anyone know how I can get the interface mod?

At the end of the thread linked to by the OP someone provides links to the four files required, neither these nor the original link work for me.
