No, a new thread is great, much easier to find for me.
Good work on the menu/ estimates. You will have some meats and rolls left, but all will get their first choices. You need sandwich fixings (onions, pickles, etc.) see the sandwich event page.
4 cans of beans is probably plenty.
Not sure what a suddenly salad kit is? Google says a pasta salad. May I strongly encourage you to do one of the pasta salads for 100 on this site? Easy, truly, and much cheaper, and you don't have to open all those little bags. You can use frozen veggies just thawed, broccoli cuts, fiesta corn, and 6 pounds of pasta and have a very easy time of it.
You will need about 6 pounds of cream cheese and about 10 pounds of thick-cut bacon, allowing 1/2 slice per 1/2.
