How far in advance can you make Jalapeno poppers?

I'm making the basic poppers stuffed with cream cheese a little cheddar cheese on top and then wrapped in bacon. We are putting them in a smoker to cook on saturday afternoon for saturday night. I've made these before but in small quantities. I need to make about a 100 this time and I work night shift so I was wanting to work on them a few at time a few days before the party. I just wanted to see if anyone had made them a couple days in advance and if they were still ok. Also...I've heard of people adding a little smokie sausage to them...anyone done this? Sounded good to me. Just put it in the middle whole?
