Fill two G1145 form. One for I-821 and if taking EAD form as well. From my experience, they had all my ead info 1 week before they actually sent me I-821 notification because I had placed G1145 on top , I-821 and last page EAD application, so G1145 didn't work for EAD.. So I would suggest,
G1145
I-821 (tps form)
G1145
Ead application.
