Hm... interesting start. Welp, time to continue reading. (BTW, do I need to know anything about Gundam Wing to understand what's going to happen in this series?)
General knowledge helps. You don't need to know much of the war history, it's more about character personalities and interactions they had. I would know that at the end of the actual movie that happened after Gundam Wing they basically all swore to never kill again. Most other stuff you can gleam from a wiki if you need to.
