Will it just click and play or will I have to do some kind of setup ?

Most likely you will need to setup. I recommend using a source port like zandronum for ease of use. Also if you use multiplayer, change your name away from "player". I personally ban people who don't change their name from that, since having a server with 5 people with the same name is retarded.
