I got my passport stamped at Denver office.
All you need is; passport, approval notice, Last/All I-94, EAD(s),AP(s). They don't care checking dates on EAD/AP/I-94. They don't care checking whether you submitted all issued EAD(s)/AP(s). Lady told me not to use EAD/AP anymore, if I have any.
They just collect those, put in the plastic back, stamp your passport, give you copies of what they have (e.g. stamped approval notice) and send for plastic processing.
Apart from waiting in the queue everything was nice and cool.
