H1B, 485 pending, travel with AP, Do I need bring H1B I-94 form

Hi, everyone:

Plan to go back China using AP, with 485 pending. Just got H1-B renewed and got a new I-94 form. Should I take that I-94 form with me and show it together with my AP? Or will I get a new I-94 when I enter US with AP?

Besides the AP, driver's licence, 485 receipt, what elso should I bring with me? Do I need to bring H1-B approval notice, or employment letter thing like that?

Sorry for asking so many questions, first time to use AP, kinf of nervious.
Experts and people traveled before with AP, please share your advise and experience.

Wish everyone have a great holiday season!
