Planning an Anime Birthday Party?

I'm trying to have a birthday party for myself with a couple of my anime loving friends. I have decided to base the party around my favorite animes. They are:

Lucky Star
Tokyo Mew Mew
Black Rock Shooter
Pokemon

We will also play some video games while we're at it. I don't really know what else to do for the party. I have some vocaloid and anime songs on my iPod so I will play those, but I have nothing else figured out.

Oh and I think I am going to try for a house party.
