Party Menu Help!

I need help!!
We're having about 30 people over to our house this Friday for a baptism ceremony/party in our backyard! I'm really looking forward to it, but I also have a lot to do before then. I agreed to take on a bookkeeping job for the next little while which starts on Thursday, Thursday night Matt and I are going out for my birthday date which we had a heck of a time scheduling, and Friday I'm not even going to be home all day! So, in light of this, I'm having to replan my menu to include more quick and/or make-ahead ideas.
There are a couple of things I know I'm going to be serving, like mini corn muffins. Super quick, super easy, and I can make them Thursday afternoon. Done.
I also know the beverage menu: mimosas, italian sodas and pink lemonade.
That's about where my knowledge ends :)
I'd love to have input about what I should serve at the party, so I'm listing all the possible selections (already pared down from an even bigger list that included homemade pitas and caviar) and the pros/cons of that dish. Let me know what you think I should do!
Sweet:
Sweet Orange Marscanpone Tartlets - the phyllo shells for this I can make three days in advance and then just fill and garnish them last minute.
Individual Stacked Pies - Pie dough cut into circles with pie filling piled on top. Easy to do a lot of varieties but while I can make the dough in advance, it would be pretty time consuming even then. Cute, though.
Cake - easy to make, picky to decorate and not individual servings. Also not "wow", except if I spend alot of time on it.
Peanut Butter-Chocolate SemiFreddo - I could make tonight and it would be out of the way, but it would be messy and hectic to serve at the time, but I still like the idea of a cold treat
Savory:
Mini Asian Cucumber Bites - a weird little Pampered Chef recipe featuring cucumbers, bacon and water chestnuts. Really yummy and very cute, but also a little labor intensive.
Mini Savory Waffles with Syrup-Sweetened Ketchup - Brunchish, but so are the Mimosas. Could make earlier on in the day and reheat but would still be pretty hands-on.
A savory phyllo tart - those phyllo shells would be so easy to make dozens of and then, again, I could just fill them at the last minute. I just don't know what to put in them.
Honey Garlic Marinated Chicken Wings - An old family recipe that I adore: throw together the night before, marinate overnight and bake all day. Very yummy, very messy
Beef Satay with Spicy Peanut Sauce - Slightly cheaper than the chicken wings, but more work. But also more trendy.

I'm thinking two sweet, one meat and one other savory. So....

What do I do?????
