It also helps to have a pull up on the RXD line as well.
On which RXD? The one on the AVR? Not needed, as the transceiver's RO is for "receiver output"....

It's not the physical proximity on the package that matters. It's the connectivity to the die. While all GND pins are connected to the die ground, the exact point of...

"Still in start up territory: 6433344" The image in your OP suggests a 104.53 us bit time. That's only -0.35% slow w.r.t. 9600 baud (104.167 us), well within tolerance.
