Have you ever made a frittatta (or maybe a breakfast strata)?. You can prep all the ingredients the day before and cook that in the AM. I think an egg dish (that can be cut up and tastes good lukewarm or hot) like that plus some muffins (bake or buy), fruit salad, and a green salad could be good additions to what you want to serve and would make a good menu.
When I do parties, I have found that it is good to have some food that doesn't have to bake in the oven. I also like to make some food ahead. You just need to have foods that reheat well. For time management, it is always good to mix some things that you find easy to prepare, or buy some things premade.
Finger foods are fun, but sometimes a lot of work (since you want to do things people don't eat every day). Sometimes I like to have fun drinks and that livens up a menu. We do a lot of gourmet sodas, hot cider, special ice tea recipes, etc. Maybe if you buy croissants, you could get some exotic jams and spreads, or do a hot chocolate bar that has fun mix ins, then you would have something different that wouldn't involve a lot of "prepping".
