Welcome home and thanks for sharing the great pic, they are adorable
Here are some of my thoughts,
I would not push the bonding with dh now, the main goal is for them is to focus on having a secure attachment with you, once that happens which could take some time, different for every child, then the attachment to dad will be easier and come more naturally.
Not sure about the no strolling suggestion? could be to avoid overstimulation,keeping their world small, and the thought of it as not a direct hands on interaction with you.
Potty training will happen alot easier after they have settled in for a while at home,would not focus on it now.
Best wishes and thanks for the pic and update!
