go according to the checklist ..
the checklist comes first, if you have signed up for the text messaging (which i highly encourage you do so) comes next, then all the forms/documents in the order of the checklist. if you have anything else to go along with the documents, that goes in the end
clip it (use actual big clips) on two sides of the package .. make it secure .. just so that nothing falls out ..
for the pictures - i suggest you put in an envelope (including your pass port pictures) and seal them .. write on them what the envelope contains ..
i know it's a alot of organizing you have to do, but atleast this way you have peace of mind that you gave them everything all organized ..
good luck ..
