VEX Direct Shipping Form Questions

I was looking at the GES shipping option for the World Championship, however it is very unclear which forms you must submit. Must you submit all the forms or only the “Required Forms”? Also, as said on page 10, must the weight be at least 100 lbs or as said on page 14 can it be less than 100 lbs? We are considering using this option so it would really help. Thanks!
