Suggestion for H1B renew or EAD application

It's my first post here....I'm sorry I cannot type Chinese from work.  :-)

Me and my hu*****and both submitted green card application through different categary (EB3 and EB2), and we both have H1B visa, both got 140 approved.  Now, my H1B visa will be expired begining of next year.  My questions are:

1. should I renew my H1B visa or apply for EAD card?

2. If I use EAD card, will that effect GC approval process if finally I have to give up my application through EB3, and go with my hu*****and's application(EB2)?

Thank you very much!
