1. The English version. International refers to non-English.
2. Click
here for the latest SoA patch. Trust me on this one.
3. It's a good idea to get ToB now. You won't miss out on any quests or gameplay, but you will be able to take advantages of enhancements/improvements made to ToB gameplay that will have a flow-on effect to SoA. Also, ToB is an add-on as well as an add-in, so there is a part of ToB that you can access while in SoA. Finally, if you get ToB you won't need to patch your game - though there's no harm done if you patch it and then install ToB on top of it.
