I think having a baby shower is a wonderful idea. Obviously, the tricky part is the "when".
Trice, I think that's a great idea. That will give you something fun to do while your dh is picking up your child...being with friends and preparing for your child's arrival.
I had a shower for my first-born, a surprise baby shower given by friends at work, and it was so incredible. Dh and I were poor starving students at the time...the pregnancy was a surprise and occurred the 2nd month of our marriage. We had no clothes, no crib, and certainly no money. My friends pulled through...even with the crib!!!
A shower can be a wonderful way to welcome your child home. Perhaps the best time would be after you're out of PGN, but waiting for the pink slip?
Just my thoughts
