Uploads are already done asynchronously, that's driver optimization 101 level stuff. It's also one of the very few operations that has an independent core to handle it (the copy engine)
Rendering shadow-maps in parallel would be pointless. If you render 2 at the same time, then each map gets half the GPU so an individual render takes twice as long, resulting in the same total time as if you gave each render 100% of the GPU and rendered in sequence.
