I finally got hitched!!!

My lovely bride (also a DM) and I have a family trip planned next month. She will use her prior name/skymiles/passport. My question is about further trips and the timeline. Obviously she needs to change with SSA and then a new driver's license. I assume that that would be enough for DL? Is it pretty flawless? Her passport is going to expire soonish, so she was just going to get a new one. How do things work with Homeland security and Global Entry?

When can I start booking new itineraries? (I want to get domestic Christmas travel, but also international travel in Jan while there is plenty of upgrade space/cheap).

Advice?
