V.P.
You've gotten great ideas- I would suggest that you give a goody bag to all the kids, not just winners of games- you will have some very upset kids. Games are grat, but winners don't need a special prize. I usually make up bags for younger kids and older kids- it doesn't have to be anything expensive. They all like sidewalk chalk, bubbles, and playdough. The kids are all bringing gifts, so they should all get something to take home for themselves.
