Most of those revards is affiliated with Adventure mode, which still has quite some time till it's release. Thereby those revards will be sent out on/after release (Expected Release Summer/Fall 2014). But I'm guessing the "in-game Costume Pack" is something that you should receive now for the regular game.
I'd recommend you e-mail Eric at Muse to sort this out, as it's him handling this. I'll PM you his e-mail.
