some puzzles about H-1B,AP,EAD

folk, Please help me out.

1. Holding H-1B, just got AP and EAD card with I-485 in pending. Whether the AP and EAD will automaticlly disable H-1B (which means you will automatically lose H-1B statuc)?

2. Holding H-1B, just got AP and EAD card with I-485 in pending. IF I USE AP TO COME BACK TO US AFTER TRAVELLING IN CHINA. Whether this activity will automaticlly disable my H-1B (which means I will automatically lose H-1B status) and I can only work as a EAD holder?

3. Holding H-1B, just got AP and EAD card with I-485 in pending. If I use AP to come back to US after GETTING MARRIED in China. (Wife is still in china) Whether I can file I-824 (follow-to-join from) for my wife and have her interviewed in CHINA to get her GC? How long will it take?
