1. You can install all 3 add-ons at once and then play them one after another, or you can install them as you progress through the game, or you can play them in reverse order – it doesn't make any difference. Each add-on will have its own unique features, and you won't be able to see the other castles and heroes in the previous campaigns.
2. If you have the Gold edition, only version 3.0 (Tribes of the East) is not patched. A patch for it was released very recently – you only need to patch that one.
3. In the game folder (or through the Start menu :)), for each version, in the FanDocuments folder (or Start-Nival-Game-Community Materials), you will find a guide and detailed documentation from fans, where you can find a lot of useful information in detail.
