its possible to renewal my EAD with I-94?

What are the documents,i need to send for renewing my EAD?

Whether i need to send my hubby and mine passport copy with visa page? Visa is expiring on sept 2012,it will create any issue for renewing my EAD,But me and husband having I-94 till july 2015.Please suggest me on this.
