H4-H1, H1 transfer, Pls help!

[waitingGC]

I will change my employer in April and transfer my H1 with my wife's H4. My wife has found some company which would sponsor her H1B. I am on EB2+485 pending. My wife is on H4(we haven't filed her 485 due to retrogression). I am very confused now. Please help me!

1. My wife's company would apply H1B on April the 1st. My new employer will transfer our H1&H4 after that. Will we have any problem here?

2. My new employer would sponsor me EB1. I have EB2+485 pending. If I apply for EB1 140+485, what will happen my old 485?

3. I am thinking to apply 140 first and if 140 gets approved, I will file 485. I am not sure if I have any risk here. Is there any chance that my EB1 485 gets denied? Do my EB2 485 and EB1 485 have the same chances to get denied?

Thank you!
