An idea for when you present the awards (and I'd be happy to help with this):

First, an announcer says "and now, to present the award for [insert award here], [insert a character here]"
Than, said character makes a short speech (in-character) and reads out the nominees (possibly just the top 4 of the category), before saying "and the winner is...[insert winner here]"
Finally, the winner's acceptance speech.

Just a thought.
