H1B Transfer while H4 EAD Pending

[aa11]

Hello, 

Need your valuable advice. 

I am on H1B and recently got I140 approved. Applied for H4 EAD for my wife and the application is pending. 

1. Can I switch job without impacting my wife's EAD?

2. Will I need to reapply her EAD after H1B transfer?

3. How many times can I extend my H1B status and wife's H4 EAD if my original I140 is never revoked?

Thank you.
