H4 EAD based on spouse's H1-B

Dear Folks,

Although, I have read about it, I would like to get your opinion and get to know your experience and thus, asking the query here.

Situation: My spouse has H1-B VISA and has travelled to US. Its first time in US and it has been 3 months.

Query 1: Can I apply for H4 along with EAD for me in premium processing?

Query 2: Does my spouse need to apply for GC for me to get EAD?
