looks like you'll have alot of food, too much? dunno...
On the mac, I would suggest these 2 things - 1) make way more sauce than you think the pasta should have - when I've made mac for a crowd, I thought I had a ridiculous amount of sauce, after cooking it was almost dry - I was frankly amazed - I purposefully over cooked the noodles so they wouldn't absorb all my liquid and it still sucked it all up!
2) consider adding crumbled bacon mixed into the mac - you say bacon mac & cheese an' people get all giddy. Cook the strips in the oven on a cookie sheet for about 10-14 min @ 425* and then either manually chop them of drop 'em in a food processor.

We shall throw our bacon wrapped all beef justice upon the wooden skewers of truth to be held on high and let them know that we will not stand for this. ~Butz
