Yavin Station

I have a free Xbox Live account, with my Xbox I am buying on Monday, I have Kotor, and I am going to download the extra content, but I was wondering if you guys could tell me what type of stuff I would find on Yavin Station. I've only heard rumors. I hear you can't get the Heart of the Guardian and Mantle of the Force until you have found all the Star Maps. Is that true? If it is it's unfortunate it's that late in the game. Is there any thing else there, like really phat Jedi Robes, if so I'd be stoked?

Aragorn Edit: Doesn't warrant it's own thread--use the General KotOR thread for specific questions, please. That said: No inventory list, but some info on the zone here.
