That looks pretty good to me. Some lawyers add in some items to show the marriage bona fides (joint property, bills, etc.) and also prior divorce decrees to show the marriage is legal.Ask a similar question
I would recommend that you have an attorney review the application prior to filing. You should only submit copies to USCIS and you will need to prove to them that both you and your husband have been maintaining H-1B status prior to filing the H-4 application (i.e., you will also need copies of recent pay stubs).
