Soooo sorry to hear this!!!
DO NOT TAKE ANYTHING WITH YOU YOU HAVEN"T UNPACKED SINCE YOU MOVED!!! If you haven't touched it - you don't need it.
If the kids have outgrown the clothes and the toys - donate or sell them.
Pack one room at a time. Label each box which room it is for.
Take pictures of valuables or collectibles and pack them individually and marked with some obscure name instead of "collectible" (especially if you are having a company come move the boxes).
Good luck!!
