I pre-ordered the deluxe version of Dragon Age on Steam.  I'm supposed to have access to special items because of both the preorder and the deluxe package, as well as the fact I imported a character from the Character generator demo.

Steam gave me three product keys and a short message that I'd be prompted to input them.  I never was.  Do I need to input these keys or were they activated once Steam installed Dragon Age, giving me access to my bonus content?

Help please.  I'm a little confused.
