You will want to discuss this with the attorney filing your greencard and H-1b. You can travel either using the H-1b or advance parole - you will want to talk with the attorney working on this the reasons to use one over the other. Your wife may enter as an H-4 if you are still using the H-1b visa. Assuming you marry prior to the issuance/approval of the greencard, your wife will also be able to obtain her greencard at the same time. However, it is essential you marry prior to the approval of the greencard.
