Party for 40, is my shopping list OK?

I'm cooking for my friend's daughter's 2nd birthday party. They're expecting about 40 people total, but I think that includes the little kids showing up. They want brisket, pulled pork, baked beans
and mac & cheese. They're handling food for the little kids as well as veggies/salads/extra sides.

Here's what I'm gonna pick up tonight unless someone chimes in that it isn't enough.

1 large packer (14lbs or more?)
2-4 butts (shooting for 25-30lbs uncooked)
4lbs dried pasta for homemade mac & cheese
7-10lbs canned pork and beans (to be doctored, probably into Keri's Hog Apple)

Am I looking OK or will I need more?

OK, I went with a 15lb packer, I have 4 butts totalling 30 lbs, 1 7lb can of Bush's baked beans for doctoring and 3 lbs of pasta for mac & cheese. I feel confident.

I figured that was going to be too much beans, but that large can was only $6.50 at Smart N Final so I figured too much is better than not enough.

Thanks guys!

Just got back, the food was a hit! The brisket went QUICK but there was plenty of leftover pulled pork, even though I only cooked 3 butts. The mac and cheese went quick as well, I didn't quite use all 4 lbs, but I filled a large foil container. There was a bunch of beans leftover, which I anticipated. I got a lot of requests to cater parties, I guess I really should go legit, as today was just a favor for a friend.
