It seems to me that if I wanted to raise the seatpost, I would need a longer bolt. Is that assessment correct? And if so, does anyone by any chance have said longer bolt?

Once you dislodge the other parts from inside the frame you'll be able to set the seat post wherever you'd like. There're a wedge and 2 expanding plate down inside.
