AP without EAD

[Utpal]

My wife is on H4 now. She has got her Advance Parole but not the EAD.
1) Can she use her AP for travel back from India ?
2) I am still on my H1 - would her travelling on AP change my employment status?
3) On the otherhand, can she stay in US if I use my EAD (she would have her AP but not the EAD)
